A source tells People.com, "Yes, they are dating and having a good time. They've been getting more open with their flirting for weeks."
According to TMZ, Smart is 24 years old. (Here's a photo of the pair backstage during Lopez's concert in the Ukraine this past summer. At the time, they were just friends. The singer and "American Idol" judge is going through a divorce from Marc Anthony. She was previously married to backup dancer Cris Judd. And some other guy.)
Smart, who's appeared on "Glee," "Step Up 3D" and as dancer on the Los Angeles nightclub circuit, bares his chiseled abs and shoulder tattoo on his Facebook page, where he describes himself as an "actor/choreographer."
(His name sounds super-fake. But if he's going after a hot commodity like J-Lo, then he's clearly not Casper Stupid.)
