A sex tape featuring Diddy and Cassie is up for sale after the rapper was hacked. The music world certainly seems to be full of sex tape rumors these days. There's the Rihanna and J-Cole video that has never surfaced; the Soulja Boy sex tape that he's denying the existence of; Lil Wayne's explicit video with a woman that looks like Nicki Minaj; and even a sex tape starring Tupac (this last one turned out not to be a rumor).

So would it really be all that surprising if Sean Combs has one of his own? According to MediaTakeOut, a group that has managed to hack into Diddy's phone or computer is trying to sell an explicit sex tape starring the rapper and his girlfriend Cassie. Cassie has had her own explicit nude photos hacked and leaked on the web in the past, and earlier this year what appeared to be a personal photo of Diddy draped in a towel and kissing Cassie hit the web.

So was that pic procured by the same group of hackers? And are the hackers trying to sell the sex tape part of the same ring responsible for the Scarlett Johansson nude photos? It's entirely possible that MTO doesn't have a real story here (it wouldn't be a first for the gossip site), but there is some evidence that Sean Combs did get hacked — the rapper is currently investigating someone who leaked his credit card information online.

The group that hacked Diddy also claims to possess photos that other celebrities sent him, and it sounds like these pics might also be extremely personal. So did Diddy have photos of Jennifer Lopez, Sienna Miller, Naomi Campbell, or some of his other celebrity conquests? MTO says that the hacker group will be releasing a list of the celebs featured in the photos later today, so stay tuned.
