Bella Thorne Back from Cannes Without Scott Disick (VIDEO)

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.
