Eminem's F-bomb escaped the censor's bleep button last night at the Grammys during a performance of "Love the Way You Lie" with Rihanna Sunday night.

Although most of his expletives were bleeped out, CBS did let this one slide.

CBS is currently still fighting a $550,000 fine from the FCC for Janet Jackson's infamous 2004 Super Bowl wardrobe malfunction.

Although they were able to catch Lady Gaga saying "holy sh*t!" during her acceptance speech as well as a curse word during Cee-Lo Green's duet with Gwyneth Paltrow, we're sure they don't want to add any more fines to their already outrageous tab!
