Casper Smart was a relative unknown before hooking up with Jennifer Lopez and becoming a familiar face in the supermarket tabloids. Now a fellow dancer from Smart's past is claiming that the Casper Smart seen in the magazines with superstar Lopez is not the man he once was.

Joshua Lee Ayers, a professional dancer who has worked with LL Cool J, Fergie, Kelly Rowland, Ludacris, Diana Ross and the cast of Glee, claims that Smart is actually gay and only dating Lopez to further his own career.

Ayers has taken to his Twitter account to denounce and expose Smart, who has been very publicly dating Lopez for the past eight months.

LOL @jessyterrero check out Ur Gay Homie@caspersmart. Know as a low key homo in hollywood!!! Ayres tweeted on March 11 with a photo of a shirtless Smart dressed in lame gold shorts, a scarf and a fur hat with an object positioned in his underwear.

He continued to tweet about Smart for months.

Someone tweeted to Smart, asking how he comes up with his choreography, to which Ayers responded He stealz them off of other choreographers..... #Biter #Fact.

He goes on to say that the truth about Smart will eventually be revealed. Sorry. I Actually know casper smart personality. I do not support him and know he's not a good person. Only if JLO knew... he tweeted later in March.

Despite saying Smart is gay, Ayers also alleged that the dancer had another girlfriend before he began dating Lopez. This girlfriend reportedly got Smart booked for the job with the 42-year-old pop diva.  

@JLevsperJLover U know casper USED/CHEATED on the Girlfriend who got him on the JLO gig right??He jus usin JLO 4 fame/success, Ayers tweeted to a fan who posted a photo of Lopez and Smart together. LMAO - jus sayin. If u really a JLO fan LOVER. U should know and be scared she us will a using , liar and cheat. :)

This supposed ex-girlfriend's name is Aisha Francis; Ayers has posted multiple photos of her on his Twitter account.

Lopez and ex-husband Marc Anthony announced their split last July. Four months later, sources confirmed she was dating the 25-year-old backup dancer.

I actually feel pretty bad for her. She has all the $ in the world and a miserable love life, 3 divorces, 2 kids and a gay BF lol, read a post Ayers retweed on June 22. 

Ayers accused Smart not only of infidelity and secret homosexuality, he also of stealing someone else's entire image. He charged that Smart stole his name, tattoos, hair style, image from someone named Jesse Casper Brown.

You can't defend Casper nor take responsibility for his shady ways in the passed [sic] and present. He must deal with the real, he tweeted on Sunday. Cuz casper is a fake dood and knows I know! He will avoid the truth threw his and Jlo's REP. was the first to report the Casper Smart charges. The couple's rep, Mark Young, responded by saying: Casper is not gay. These comment are born from envy and jealousy. It must be a slow news day.

In the March issue of Vogue magazine, Lopez opened up a bit about her relationship with Smart. He's adorable, she said. But you already see that. He's a good egg. I don't want to talk about it too much. It's my private thing. 

Lopez might have kept mum at the time, but her longtime manager Benny Medina was more forthcoming. The thing that I always sort of wished is that she would give herself time to just naturally meet someone, instead of having obsessive guys pursue her, said Medina, who has seen Lopez through a slew of relationships, including Ojani Noa, Diddy, Chris Judd, Ben Affleck and Marc Anthony.

The ease with which that obsession becomes a relationship I think sometimes works against her ability to have a real meaningful relationship. And she never half does anything. When she commits to anything in her work, her life, or her relationships, she is in it, he told Vogue.

She's not oblivious to her own reality right now, as in, 'Damn, I'm 42 with a 24-year-old. Why?' he added. We talked about it yesterday. She was just like, 'It's not even the age, Benny. It's that I just came out of a relationship where I felt like I was kind of not getting what I needed. And I'm open! So somebody who steps in right now and is actually touching me in a way.' It's very fertile ground.
