Katy Perry

Katy Perry and Russell Brand were exchanging four-letter words rather than hugs and snuggles at the holiday -- maybe. Unidentified troublemakers are insinuating that a huge, nasty argument occurred.

It was Christmastime fireworks for Katy Perry and Russell Brand this year - but not the good kind! After planning to whisk her family via private jet to husband Brand's London hometown for the holidays, Perry, 27, changed course, opting to fly to Hawaii with friends.

"They had a massive fight," Us Weekly an insider tells. "She was like, 'F--k you. I'm going to do my own thing.' Russell replied, 'Fine, f--k you too.'"
