It’s not all Charlie work. Sean “Diddy” Combs is set to guest star in the 8th season of It’s Always Sunny in Philadelphia. Combs will be shooting his guest spot this week and the new season of the FX show is set to premiere on October 11th. What role Combs will play is still under wraps but this season Charlie will be reunited with his biological father only to learn he’s dating his longtime crush, the waitress. It would be great if Charlie’s father turned out to be Diddy. It would also be great if they escalated the kitten mittens storyline and pitted them against dog boots. But I’m no writer, I just know what I like.
