We can hardly get enough of the unpredictable Bella Thorne ... and apparently a lot of other people are pretty interested in her daily musings, too, as evidenced by her huge social media following AND by her surprising hookup and subsequent trip to Cannes with Scott Disick.

Who woulda thunk the nose-pierced, tattooed former Disney star would get down and dirty with the Lord and that he'd invite her to the south of France?! Even Scott never thought he'd do it and as soon as former flame Chloe Bartoli showed up, Scott dumped Bella without skipping a beat. Of course once he enjoyed a few days with Chloe, he moved on to six or seven other girls, too.

So back to Bella -- after she got kicked to the curb by Scott and flew back to LA, she picked up where she left off with ex-boyfriend Greg Sulkin, posting a throwback of the two cuddling and captioning it, "Happy birthday Gregg!!!! I love you. Always been such a wonderful person:) glad we are here through thick and thin. Let’s party you old man!!"

The two supposedly broke up last August and immediately after, Thorne announced she's bisexual. Bet Scott didn't mind that! Anywho ... what what happened when we asked Bella if she was gonna hook up with Scott again ...
