On Tuesday (May 21) a judge in Desoto County, Mississippi issued an arrest warrant for rapper Tim Dog ... which is interesting, considering the notorious "F--- Compton" MC supposedly died in February.

However, according to the Desoto County District Attorney's office, a death certificate has never been filed, and no one seems to know where Tim Dog — real name Timothy Blair &#8212 was buried. Which means, in their eyes, he is still very much alive, and may have faked his death to avoid court-mandated payments to a woman he stole $32,000 from in 2011.

"I need proof. I need a death certificate showing that he's dead, because as far as I'm concerned, he's alive," prosecutor Steven Jubera told Memphis news channel 3 WREG. "Nobody said where he died, nobody said where he was buried, which is very odd for an obituary."

Blair plead guilty to grand larceny two years ago and was given five years' probation. A judge also ordered him to repay $19,000 to a Mississippi woman he defrauded in a financial scheme within the probation period, but that woman says the payments stopped when he was reported dead in February. Suspicious, she sent a friend down to Atlanta, where Blair allegedly died, to find a death certificate, but that search came up empty.

After speaking with the victim, WREG hired a private investigator to look into the matter, who couldn't locate a death certificate either, and told the station that, as of April, there was also an active address for Blair in Atlanta.

Some artists would go ballistic if they found out some joker was impersonating them on the red carpet at a major media event. Not Psy, though.

The genial South Korean rapper had a surprisingly jovial reaction to the fake 
 tweeting, "Seems like there's another ME at Cannes ... say HI to him @scooterbraun lol #PsyinSingapore."

He later uploaded a photo of the phony, who was spotted by manager Scooter Braun, and, well, you could see why some people might have been fooled.

The fake Psy, who wore the rapper's signature round glasses and ill-fitting suit, has been living it up around Cannes for several days as celebrities and journalists hit the town for the annual film festival. According to the Atlantic Wire, the as-yet-unidentified imposter went to parties, posed with celebrities and appeared in a video for French radio station Radio Prestige where he showed the host how to do the "Gangnam Style" dance.

Among those who got duped into posing with the pretender were actress Naomi Harris ("Skyfall"), actor Adrien Brody and Portland Trailblazers player Nicolas Batum. He also reportedly made his way into parties at the Carlton hotel, the VIP Room and Martinez beach, as well as attending a secret bash thrown by millionaire oil baron and fashion designer Goga Ashkenazi at Le Baron, where he grabbed a mike behind the DJ booth at the soiree attended by Karolina Kurkova and Rosario Dawson.

A spokesperson for Psy's management could not be reached for comment on the incident.

The Wire also reported that he was "scamming" ...

What do you get when you take the Backstreet Boys, and then toss in Jesse McCartney and DJ Pauly D for good measure? "A lot of testosterone," according to BSB's Howie Dorough.

The boy band recently dished to MTV News about their upcoming summer tour, and told us that while they certainly aren't newbies when it comes to the road, their experience means they feel ready for anything. In 2011 and 2012, they went on massive tours with New Kids on the Block, and those jaunts were something like a traveling pop wolf pack.

"We just finished a tour with nine of us," A.J. McLean said of the NKTOTBSB run, adding that for the new tour, Pauly D being on the lineup ensures there will be "lots of fist pumping going on."

The In a World Like This Tour celebrates the boy band's 20-year anniversary and kicks off August 2 in Chicago. It will cross North America for five weeks before wrapping up September 8 in San Francisco.

"We're excited [because] we actually worked with Jesse before," Nick Carter said of McCartney, who opened for the guys on their Never Gone Tour in 2005. "We had a great time with him and, obviously, the relationship has stood."

"And Pauly D has a great fanbase. Now it'll be Double Ds, between me and him, on the road," Howie D joked.

Did One Direction Do The Backstreet Boys Justice?

Just days before the tour kicks off on July 30, the band will release their album, In a World Like This. (Their ...

In a cameo appearance, Oscar nominee Melissa McCarthy has an intimate moment with Zach Galifianakis' Alan in a Las Vegas pawn shop, and from there, things get real.

"I didn't know Melissa, and we had just met kind of met that day," Galifianakis said when MTV News spoke with him in Las Vegas. "Sometimes you get lucky enough to have clicked with another actor or actress, and we just, I don't know, felt like we had known each other for a long time. That helped."

The connection must have at least helped during the scene, which has Alan taking the lollipop from his mouth and seductively placing it into McCarthy's, in order to get the information he needs about the location of Mr. Chow.

Galifianakis' co-star, Bradley Cooper, agreed that McCarthy brought something special to the set.

"There's something about [McCarthy] and John Goodman especially," he said. "They come on set and bring an energy. It's amazing because there's a set structure and a set energy with the three of us, but Melissa would come on, and as an actress, she's just cool, unflappable energy. She set the tone actually. She really is a very powerful performer."
