Sean "Diddy" Combs was hospitalized early this morning due to an extreme migraine. 

Diddy hosted a Grammy after-party last night at the Playboy Mansion. When he got home, he developed a migraine so bad his friends had to drive him to a UCLA emergency room to get him checked out.

Diddy is home and feeling much better. A source says the migraine had nothing to do with activities that went on at the party.
