Casper is a ‘Manipulator’: Close Friend of Smart Warns Jennifer Lopez

Jennifer Lopez doesn't have the best luck with love, but this time, she is evidently smitten with her new found boyfriend, Casper Smart. But as people question his sincerity, his former best friend comes up and brands Casper as a "manipulator."

The 42-year-old actress singer is currently on tour, and while she kept her children close, she also promoted Casper Smart to be the top choreographer for her concerts. J Lo seems to pour in a lot of trust to her younger boyfriend, but a former best friend of Smart warns that Lopez shouldn't trust him.

Josh Ayers, a back-up dancer, said that Jennifer shouldn't trust Casper completely. Ayers claims that Casper will do just about everything that the singer wants as long as it furthers his career.

"He's willing to do whatever Jennifer wants as long as it furthers his own career," Ayers told In Touch Weekly.

Ayers who have been close with Casper for years said that he has seen how the dancer manipulates women to get what he wants. The 25-year-old dancer choreographer had a girlfriend for two years before hooking up with the American Idol judge.

According to Ayers, Casper's then girlfriend Aisha Francis, helped him land a part in Jennifer's music video "Dance Again." That's when the two first met. Ayers added that his ex best friend "just got lucky."

"Aisha was really good to Casper. He used her to get what he wanted," Josh said. He added that Aisha was in shock when she learned on TV last December that Casper and Jennifer are together.

Casper who is evidently showered with gifts, including the customized car he got on his birthday, said that the relationship with Jennifer happened "spontaneously." Jennifer and Casper has not yet commented on Ayers' claims.
