The Craziest Celeb Twitter Wars Ever! See Who's Feuded

Nick Cannon took on the media amidst rumors that he's splitting from Mariah Carey. "Because my family & I haven't been forthcoming with personal information, people are quick to paint negative pictures and spread rumours," he said. "Others have lives, families,  and careers and for the media to slander them is down right evil and illegal..."

After Amanda tweeted that Chris Brown beat Rihanna because she wasn't pretty enough (yikes), Ri shut it down with "Ya see what happens when they cancel Intervention?" Zing.

These two constantly fight over their mutual lady-love, Rihanna, and have even come to physical blows. But their favorite mode of fighting is thinly-veiled jabs at each other on Twitter.

Farrah was wildly angry about Kourtney's second pregnancy for some reason, and wondered aloud on Twitter, "did she not learn anything from TEEN MOM?" To which Kourt reminded her that she was 32 years old.

It's only natural for two British boy bands to have a rivalry. Less natural is the most recent barb, with a 1D-er swearing that a member of The Wanted wets the bed. Mature!

After Kendall posted a whiny tweet about not getting her way, Frances shot back calling her a "self-absorbed idiot" and other typical insults lobbed at the Kardashians.

These two ladies have plenty of reasons to war in real life, but they often choose to work out their issues on Twitter, even prompting LeAnn to complain recently that Twitter rants are "so 2012."

Again, Twitter is the least of this on-again, off-again couple's problems, but you can usually track the current state of their relationship by whether or not they're following each other at that time!
