Antibes, France - Joe Jonas was just spotted in the south of France looking flirty with an actor 27 years his senior!

They were later joined by Joe's brother Kevin and model mom Heidi Klum.

But what is really going on between the two? One insider speaks of a purely platonic relationship.

"Demi and Joe have struck up a friendship. They have mutual friends and they bonded," the source told Page Six.

In any case, both are currently single so anything is possible!

Joe recently called it quits with model Stormi Bree after dating for six months following his tumultuous split from ex-wife Sophie Turner.

Demi Moore has herself been married three times to Freddy Moore, Bruce Willis, and then Ashton Kutcher.

The Ghost star had a significant age gap with a much younger Ashton, so a romance with Joe wouldn't be out of the realm of possibility!
