Bella Thorne Back from Cannes ... Scott's a Joke

Bella Thorne has Scott Disick in her rear view ... and she's pretty happy about it.

The actress was back in the U.S. of A with sister Dani and a friend ... getting her Saturday breakfast fix when she laughed off a photog's comment about Scott.

As we reported ... the 19-year-old's pissed she was used by Disick -- almost twice her age -- and decided to bail early on the trip.

As for Scott ... it's clear he doesn't care either, because he's been with at least 2 other chicks since saying sayonara to Bella.
