MTV Star -- Hollywood's Ditching the Lakers ... for the Clippers

Hollywood celebrities are abandoning the Lakers in droves ... and they're defecting to the rival L.A. Clippers ... so says MTV star Chris "Drama" Pfaff.

Pfaff -- who stars on a slew of MTV shows including "Fantasy Factory" and "Ridiculousness" -- was out in NYC yesterday when he admitted he's hitching a ride on the Clippers bandwagon.

"Clippers games used to be empty," Drama said ... but that was before Blake Griffin, CP3 and company began dominating.

Now, according to Pfaff, Lob City games are packed with celebrities and floor seats are nearly impossible to lock up.
