Admittedly, we've only heard a few details to date of 'It's Always Sunny In Philadelphia' Season 8.  For instance, we know that Sean "Diddy" Combs will take on an unknown role for an episode, and that the October 11 premiere will see Charlie finally meeting up with his biological father (with a heart-breaking twist), but if FX was planning to replaice the entire cast of the show, don't you think we would have heard about it?  Apparently not!

Move over 'It's Always Sunny In Philadelphia' cast, you're about to be replaced!  As the latest promo for the long-running FX comedy reveals, the network has opted to go in a decidedly insane direction, recasting the roles of Mac, Dee, Charlie, Dennis and Frank with former child star Haley Joel Osment, rapper Xzibit, 'Full House's Candace Cameron, UFC star Chael Sonnen, and Andrew Dice Clay!

Yep, you're reading that correctly.  The blonde girl from 'Full House' will play Charlie, and Xzibit will play the blonde Dee.  It's all in good fun, as the behind the scenes featurette below reveals, but who's ready to meet the new cast of 'It's Always Sunny In Philadelphia' Season 8?

Otherwise, we’ve only learned a few scant details of ‘It’s Always Sunny in Philadelphia’ season 8, though we at least know for certain that this year won’t be the last we’ve seen of the gang from ‘Sunny.’  Take a look at the promos below, and tell us what you want to see from the new season in the comments!
