A former co-worker of Casper Smart, the world's most famous backup dancer next to Kevin Federline, claims that the 25-year old is playing for the other team. In what seems like a serious case of sour grapes, dancer Joshua Lee Ayers is on a major smear campaign to destroy Smart. Back in March, he accused the boytoy of music sensation Jennifer Lopez of ripping his choreography off other dancers. He then posted a photo of Smart surrounded by a group of shirtless men on his Twitter saying, "LOL @jessyterrero check out Ur Gay Homie @caspersmart. Know as a low key homo in hollywood!!!" Of course, the attached photo featured Smart in a shimmery belt, a scarf, a hat and short gold shorts with a bottle stuffed in them to imply some funny stuff. Proving he definitely knows how to beat the crap out of a dead horse, Ayers also Tweeted, "@JLevsperJLover @Caspersmart U know casper USED/CHEATED on the Girlfriend who got him on the JLO gig right??He jus usin JLO 4 fame/success." He also wrote of the man who's been wooing Jenny from the Block, "I know what I know, Not love, a lot of business and public relations." Up until now, neither Smart nor Lopez have commented on the allegations, including those questioning Smart's sexuality. However, the couple's rep laughed in the face of the rumors, telling Radaronline, "Casper is not gay. These comment are born from envy and jealousy. It must be a slow news day." Sounds like Ayers should lay off the Haterade.
