Slapfights

Things went down (to subterranean levels) on the Twittersphere over the weekend, as Chris Brown responded to taunting from comedy writer Jenny Johnson by completely deleting his account, which is the online version of "I'm taking my ball and going home."

It happens to the best of us. Sometimes it's just so hard to keep celebrities from getting into spats at our $3 million birthday parties. Just ask Leonardo DiCaprio. At his posh New York birthday celebration, there was a bit of a tiff between a couple of names you might recognize: Robert De Niro and Jay-Z.

It’s no Don Lemon vs. Jonah Hill tete-a-tete, but it looks as though Hoda and Kathie Lee, aka the ladies of the 17th hour of ‘The Today Show,’ are having a bit of a spat with Chelsea Handler.

It’s wedgies and wet willies and slapfights oh my for CNN anchor Don Lemon and actor Jonah Hill -- because the two are embroiled in a junior high-esque Twitter battle and we’re the unwilling audience. Basically, the effeminate kid and the fat kid are rolling around on the gym floor scratching, pulling hair and crying. And we're pretty sure someone's glasses got stepped on.

Unlikely BFFs and singers Katy Perry and Rihanna are reportedly having a bit of a tiff right now over a man. And not in the usual way women fight over men in soap operas and sitcoms -- this stems from Rihanna letting abusive ex-boyfriend Chris Brown back in her life.

It's the battle of the mediocre musicians as Nickelback front-man -- and Avril Lavigne's fiance -- Chad Kroeger takes on former Sum 41 lead -- and Avril's ex-husband -- Deryck Whibley. Did you follow all that?

So she has little patience for the Nicki-come-latelys of dubious chops -- especially when they mouth off to established singers. The legendary Fleetwood Mac icon recently weighed in on the epic 'American Idol' battle between judges Mariah Carey and Nicki Minaj, saying that if the rainbow-hued pop

A while back, there were murmurings that some diva-licious sparring was already happening between Mariah Carey and Nicki Minaj on the set of 'American Idol.' At the time, the public was given a gentle pat on the head and told that no, none of those rumors were true so we should just run along and play because, really, Mommy and Daddy still loved each other so everything was fine just fine. But now

The next season of the waning talent search show ‘American Idol’ began taping on Sunday, and after working their way down a long list of possible judges, the producers ended up with a panel that seems to include one too many divas -- and we can only hope the fireworks make it to air.

It's turning into a real beyotch-fest between Lindsay Lohan and Amanda Bynes, as both "actresses" are apparently pissed that their trainwrecky lives have caused outsiders to compare them to one another. Ladies, we're happy to referee and settle this nonsense: You're both a mess.
