Secret dates: Are Jennifer Lopez and Casper Smart back ON?

The couple – who split last summer after allegations he’d been flirting with a transgender model Sofie Vissa – were snapped together in Los Angeles on Thursday night.

At one point Casper, 27, even put his arm around the 45-year-old. (SCREAM).

Now, he could have just been giving her a matey hug (like you would to a friend if they were cold) but looking at the evidence…we think not.

Don't miss!

Bizarrely, J-Lo appeared to be crashing a meeting between Casper and Nick Jonas. The guys were at the Z Zegna & GQ event in Hollywood before Casper met up with Jen and went to the nearby Hotel Café.

Casper worked as the choreographer for Jen’s Dance Again tour in 2012 (he was back up dancer before that) and he dated the Love Don’t Cost A Thing singer for two years before they split.

Last month, mum-of-two Jen hinted she was back on the market saying: “I think being on my own has been really great for me. There was a time where I was just like ‘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.”

She did add however that she had “no announcements to make” at that time.

What about now, Jen?
