Singer R. Kelly has been charged with two counts of engaging in prostitution with a person under 18 in Minnesota, prosecutors said Monday.Hennepin County Attorney Mike Freeman announced the charges against the performer, whose legal name is Robert Sylvester Kelly.Kelly is being charged by a summons, Freeman said, so it is unclear when he will respond to the new charges. His attorney has said it's not clear if his client has even met the woman and says this might be a case of "revisionist history."Freeman said the criminal complaint details an incident that occurred in July 2001 after a minor asked the singer for an autograph at a promotional event.Kelly gave the girl, then 17, his autograph and a phone number, the complaint states. When she called, she was directed to his hotel in Minneapolis and was met by someone she believed was a male member of his staff.The complaint says that when she met Kelly, the two made small talk before he gave her 0 to dance for him. After settling on the amount, she agreed. He took off her clothes and then his, and he touched her sexually while she danced, the documents say.He gave the victim VIP tickets to his concert, the complaint says. That enabled her to attend the 18+ concert without paying or showing her ID.The girl said that she discussed going to Chicago with Kelly but that the two lost contact after he changed the number he had given her, Freeman said.She contacted law enforcement in January to report the encounter, he said, after other allegations against Kelly surfaced. Attorneys corroborated some of her account with her brother, who saw her at Kelly's 2001 concert and confirmed that she told him she had been paid to dance for the singer.He said she didn't go into detail and he did not press her because she seemed uncomfortable talking about it."It is despicable that Mr. Kelly used his fame in order to prey on underaged girls," Freeman said in a statement.With charges pending against Kelly in New York and Illinois, Freeman said it's unclear when he will appear in court in Minnesota."While there are more numerous charges in the Illinois and federal cases, we wanted to make sure that our victim here in Minneapolis also receives a measure of justice," he said in a statement.Doug Anton, one of Kelly's attorneys, responded to the latest charges."Frankly I don't understand where the criminal activity exists in this matter. But I believe this highlights what has now become the absurdity of The bulk of the charges against our client.""When a top law-enforcement figure makes a public cry for the world to come and be famous by telling their sordid story, true or not, it inherently invites people to create revisionist history and put a different label on simple fan rockstar encounters."Anton said he didn't know if Kelly had ever met the woman."All we know is that yet another person has come forward either by their own desire or by being dragged in to the fray by prosecutors looking to make a name for themselves."Kelly pleaded not guilty to other charges FridayThe Minnesota indictment is the latest in a tangle of charges against Kelly, who's faced accusations of abuse and manipulation of underage girls and women for more than 20 years.On Friday, he pleaded not guilty in New York on several counts of racketeering, kidnapping, forced labor and sexual exploitation of a child. He was indicted in July by a federal court on accusations of transporting women and girls across state lines for "illegal sexual activity."Of the five unnamed women referenced in the indictment, three were minors.That indictment also alleges that he knowingly exposed at least one person to a sexually transmitted disease without disclosing it.He was indicted by grand juries in Illinois and New York in July on charges of recruiting women for sex, persuading people to conceal his sexual misconduct with teenagers, and buying back tapes that show him having sex with underage girls.He pleaded not guilty to the 13-count indictment in Illinois, which included four counts of producing child pornography and five counts of enticement of a minor to engage in criminal sexual activity.Kelly was also accused of videotaping himself having sex with at least four underage girls as far back as 1998.He'll next appear in Chicago court on September 4 for a status hearing on those charges.In February, he pleaded not guilty to an Illinois state court's charges: 10 counts of aggravated criminal sexual abuse against four people, including three underage girls. He was released on 0,000 bond but arrested and jailed in March after, authorities say, he failed to pay more than 0,000 in child support to his ex-wife. He was released days later after an undisclosed person paid the money owed.Kelly has remained in custody since July, awaiting trial on the 13-count indictment. 4851

Revenge is sweet. But Mark Rober's glitter bomb trap for package thieves proves it can be a bit messy, too.Rober is clearly a smart guy; a former NASA engineer, he worked on the Mars Curiosity rover.But for anyone who's gotten a package stolen off a doorstep, he's now a hero."Something needs to be done to take a stance against dishonest punks like this," Rober said in a now-viral YouTube video.After having a package stolen from his doorstep, Rober decided to use his engineering background to serve up some retribution on would-be thieves."If anyone was going to make a revenge bait package and over-engineer the crap out of it, it was going to be me," he said.The package would contain a pound of fine glitter plus some potent fart spray. The glitter would burst out when opened; the latter would spray five times, every 30 seconds.But Robert went one step further -- including four phones recording the thieves' reactions. A GPS tracker in the phones would let him know where a package ultimately ended up.If he couldn't recover the package, the video would at least automatically upload to the cloud.Once completed, he slapped a packing label addressed from the "Home Alone" character Kevin McCallister to movie villains Harry and Marv -- a nice, figurative bow on the present.Then Rober just needed to wait and let the package rain pain.In the YouTube video, some "victims" opened packages in their cars, with glitter being tossed into every nook and cranny. Others opened packages in their houses; one even was even filmed trying to vacuum the mess up.Still, package thieves remain a problem; click 1620

Serena Williams and Naomi Osaka — the grand slam leader in the professional tennis era and newcomer who had surged to the last two majors — both exited the French Open on Saturday in a double shock.Osaka was the first to depart in the afternoon 6-4 and 6-2 to Katerina Siniakova of the Czech Republic before Williams fell to fellow American Sofia Kenin 6-2 and 7-5 in a dramatic evening contest.Williams was short of matches entering the French Open, completing a mere three after her eventful Australian Open that ended with an ankle injury in a quarterfinal defeat.Illness, but more prominently of late, a knee injury have kept the winner of 23 majors on the sidelines.Yet any tournament the 37-year-old plays in is one she can win. And when Williams recovered from a set and break down to lead her 35th-ranked rival 5-4 in the second set, few would have bet against her.Her smooth, potent serve started to click and the 10th seed had the fans on Philippe Chatrier court behind her, especially as Kenin contested several line calls.But her 20-year-old foe, born in Moscow, hung in there and broke for 6-5 in a game that began with Williams erring long on a forehand with Kenin stranded.Williams had one more chance but sent a forehand wide on break point. Then on a second match point, her backhand sailed long.Osaka, meanwhile, admitted the French Open was just too much to handle.The world No. 1 saw her bid to become the first female player since her idol Williams in 2015 to claim three straight majors come to an end.Different feeling"Definitely I think this tournament I have had a feeling that was different to the other grand slams, or every other grand slam that I have played, because usually I find it very freeing and fun, and this time around I was kind of tense the entire time," Osaka told reporters.The fatigue that Osaka said she felt against Siniakova might have been a result. And she suspected headaches she experienced earlier at the clay-court major were because of stress.Still, her level of disappointment at exiting was off the charts."It would go from one to 10 and I'm like at a 100 right now," said Osaka.When Osaka remarked before the tournament that she sought a calendar year grand slam -- last achieved by Steffi Graf in 1988 -- it could have been interpreted as a tongue in cheek comment or at least a goal for further down the road.Osaka is still only 21.Thinking about calendar year slamBut she clearly focused on doing it this year, which she called a mistake."I think I was overthinking this calendar slam," said Osaka. "For me this is something that I have wanted to do forever, but I think I have to think about it like if it was that easy, everyone would have done it."I just have to keep training hard and put myself in a position again to do it hopefully."Osaka is adapting to the clay but she is a quick study, evidenced by a 7-1 record on the surface this season entering the French Open.That combined with her performances at the US Open -- 3000
