After proving she had little to contribute to the film or starfucking industries, Jessica Simpson finally realised she should keep her pretty-but-pretty-dumb mouth shut for the time being and instead let her t-shirts do the talking, angering PETA in the process. Though the feisty baby seal saviors have their fair share of enemies, they've also impressively managed to get celebrity spokespeople like Alec Baldwin and Eva Mendes to embarrass themselves in public by demanding the public do drugs (Baldwin) or taking off their clothes in the name of fur (Mendes). So naturally, Simpson's public cry for attention irked PETA's most compassionate celebrity nudist, Pamela Anderson, who called her fellow talent-challenged blonde "a bitch and whore" on a radio show. But this is far from the first time Jessica has ruffled another starlet's feathers just by being Jessica. We took a look back at the many ways Simpson has made herself a household name not by selling records or movie tickets, but by starring in her own personal Catfights franchise.

As none other than Defamer first reported back in April of 2006, the newly single Simpson handled her pouty grief by shoving her cleavage in scented cinema revolutionary Brett Ratner's smelly face, to the dismay of rumoured Ratner tossaway Lindsay Lohan. After a Simpson hanger-on called Lohan a "bitch," the then-closeted lesbian allegedly lunged towards their table, held back by the heroic hack himself. A year later, entrenched in John Mayer's predatory grip, Jessica was said to have declared war against her own sister Ashlee after Mayer got the two mixed up in old photos. The rivalry ended with Jessica stating to the press that she was "no longer the girl with potential," but a "blessed butterfly" instead. Triumph! And later that year, the NY Post claimed the amnesia-ridden Jessica became furious after hearing engaged Eva Longoria had dared to be "friendly and polite" to then-ex Mayer, and went on a name-calling rant through New York.

Our favourite tale, however, occurred right on the heels of her anti-PETA message tee bomb drop. Some gossips say the shirt had nothing to do with fuzzy wuzzies or pro-fur campaigns, but was meant as a message to Jesus fan and Tony Romo ex, Carrie Underwood. Underwood won the group's infamous Leno-monologue-staple Sexiest Vegetarian title back in 2005, and Simpson has supposedly been jealous of her whipped boyfriend's ex since day one of their ridiculous union. So in the end, Anderson should probably put the venom away and align with Simpson — they're both failed actresses whose only chance of maintaining "celebrity" is shoving their ample cleavage in the faces of hacks who'll give them their precious screen time.
