Soooomebody's desperate! And it looks like it's both Scott Disick AND Bella Thorne!

We're not sure which is worse and more embarrassing -- that Scott went back to the very girl he dissed in Cannes or that Bella went back after being kicked to the curb! Whatever ... these two can't stay away from each other, it seems, as bad girl Bella posted a video of herself eating hamburgers in Scott's back yard on Wednesday and then the two were out partying at 1Oak hours later!

As per usual, Bella brought along a pal, though this time is wasn't her sister. Odd that Scott always wants TWO girls ...
