Is J.Lo's boy toy hiding a big secret from his lady love? If you believe fellow dancer Josh Ayers, the answer is yes...

Ayers is a performer at Boulevard3 - the same club Casper Smart used to dance for - and he claims Jennifer Lopez's rebound romance is a sham, because her beau is secretly gay and using her for fame and fortune.

Ayers has made repeated attacks against Smart on his Twitter account, posting these pictures in March with the caption, "Check out Ur boy... And his low key homo ways." Smart is seen posing shirtless while donning gold hot pants, a neck scarf, and a suggestive bulge in his pants, but we're inclined to believe this pic was taken out of context!

We think this is a classic case of jealousy, because there's no fooling someone like Jenny from the Block!
