Celebrity Jennifer Lopez and Casper Smart Share Quick Kiss on Her TV Set It looks like Smart has visited Lopez more than once on the set of her new show By Adam Carlson Published on June 6, 2015 10:25 AM Share Tweet Pin Email Photo: Splash News Online These two just keep everyone guessing. Jennifer Lopez was seen sharing a quick kiss with former flame (and current #mancrush) Casper Smart while he visited her on the set of Shades of Blue in New York earlier this week. The on-off pair have remained close after their summer break-up. A Lopez friend told PEOPLE last year, “Just because it ended didn’t mean they had to be enemies. She cares for him very much. He’s a good guy. He’s really a very good, stand-up guy.” Smart, 28, has been visiting Lopez, 45, on the set of her new police drama, Shades of Blue, judging by their smooch and shots of them holding hands Thursday.

I’m kind of not [single], but I kind of am,” she told the host.
