Is Jennifer Lopez' relationship with Casper Smart on the rocks? A shocking news by TheDirty.com has revealed that "American Idol" judge's young lover is reportedly cheating on her with a transsexual woman.

Lopez hit the headlines late last year after it was revealed she was dating 27-year old Casper Smart. She had previously been married to singer Mark Anthony, whom she also has two children.

Currently, the "Jenny from the Block" singer is back on the tabloids after it has been reported that her much younger lover is cheating on the 44-year-old singer with a transsexual model.

The Web site stunned the avid readers with its claims that Smart has been having intimate encounters with a Sofia Vissa, a transsexual model. The tipster sent in a message to Nik Richie, owner of the Web site, which the latter then posted online for everyone to see.

""Nik, sooo my homegirl has been talking and linking up with Casper Smart for a week now... they met online and I guess they Both follow each other.... she texted me saying they exchanged pictures XXX's...and what not....I'm liked shocked...didn't know he was down for Us beautiful Transsexual WOMEN," the source revealed to TheDirty.com

The transsexual model allegedly has nude photos of Jennifer Lopez' boy toy taken on May 19 and she is also auctioning them off to the highest bidder.
