s love is back in the air for Jennifer Lopez and ex-beau Casper Smart -- or are there just no hard feelings between them?

 

The pair split up last April after meeting in 2012 on J.Lo's Dance Again Tour, where Smart served as a backup dancer -- but on Thursday night, Jenny from the Block was spotted at The Hotel Cafe bar in Hollywood with her ex. Smart reportedly rubbed shoulders with Joe Jonas, 'Glee; actor Chord Overstreet, Bow Wow and other stars.

There were reports that the two reconnected in Las Vegas on New Years Eve. "I think being on my own has been really great for me...There was a time where I was just like 'Ehhh, I'm just not going to deal with anybody, I just want to be on my own.' Now I'm getting back into the mix. For right now, I just have no announcements to make," Lopez told Us Weekly in January.
