Diddy and Cassie Are Back Together

Last year, Diddy and his longtime girlfriend Cassie broke up - Cassie moved on and started dating her personal trainer, Alex Fine. She even moved into his Malibu home!

However, the couple split up last month and it looks like Cassie and Diddy started dating again.

According to sources, Diddy claims that he's "changed" and this time he promises to marry Cassie.

How is everyone so sure that they're back together?! CASSIE'S WEAVE!

People seem to think that there is no way Alex could have afforded such a good quality weave and it must be from Diddy's money.

I guess only time will tell if they really are back together!
