Diddy was hospitalized this AM for an extreme migraine. The mogul hosted a post-Grammy party at the Playboy Mansion Sunday night. After the party, Diddy went home and got a massive headache.
Diddy’s entourage became so concerned … they drove him to the UCLA  emergency room — btw, the same place where Michael Jackson was pronounced dead.
Diddy was treated and is back at home, feeling a lot better. A Diddy source says the migraine was unrelated to anything that went down at the Mansion.
