From a heated exchange between Perez Hilton and will.i.am that led to a rumble, to another Real Housewives of New Jersey star hating Danielle Staub, to Terrell Owens being told off by a Playboy model, this week had some quality celeb feuds.
Oh, and don't forget Mark Sanford feuding ... with brainpower and morals during his affair with Maria Belen Chapur. Side note: Jon and Kate Gosselin have been removed from this list, as their "feud" ended in divorce. So it's over. With no winner.
