Now this rumor about Diddy and Cassie being romantically involved has been going around for awhile, and I must admit it would make perfect sense b/c why else would he keep her talentless ass signed to his record label? According to a close source of them both, “Diddy and Cassie were definitely together. They were all over each other and didn’t leave each other’s side the whole night.” Now I am not sure how true this is because you never know with these CLOSE SOURCES, but as I said previously I wouldn't put it past neither one of them.
