Any time celebrities fight, it's pretty funny. From Amanda Bynes to Jon Hamm to Justin Bieber, celebrity cat-fights get, well, catty, and quick. Here's a list of the oddest among them.

Robert De Niro vs. Jay-Z

Apparently, Hova wouldn't return Robert De Niro's calls, which has, at this point, led to a feud in which both sides have called each other out, and much bad blood has shed between them. However, I'm still left wondering why De Niro was calling Jay-Z to begin with. Anybody? No?

Lady Gaga vs. Madonna AND Kelly Osbourne

DId anyone know Lady Gaga was so combative? In actuality, it seems like both Kelly Osbourne and Madge came down with a bad case of green with envy. Here's what happened. Madonna accused Gaga of copying her, although she couldn't prove it, and Kelly called Gaga's fans "the worst," which seems a little unfair coming from an Osbourne. But Gaga responded to each of them, which kind of brought her down to their level. Shame on you all, ladies, shame on you all.

Donald Trump vs. Rosie O'Donnell

These two have been feuding for YEARS. This fight has been happening since I was in single digits, and I'm pretty sure it's older than Donald Trump's wife. God even knows what they're arguing about anymore. I wish these two would just kiss and make up or settle it like men, as long as it damn well DIES.

Amanda Bynes vs. Everyone Ever

Where to even start. Amanda has called out the Obamas, Drake, her dad, her sister, RuPaul, and so, so many more. It feels sort of like the "if a tree falls in the woods" question: if Amanda Bynes calls you ugly, and no one cares, is it still a feud?

Jon Hamm vs. Kim Kardashian

This is weirdly disappointing for Jon Hamm, and definitely a high point for Kim Kardashian. Hamm was pretty harsh, saying, "Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f—ing idiot is a valuable commodity in this culture because you're rewarded significantly." I mean ... c'mon, we know you're Don Draper, but you're also talking about real people. Not so nice.

Anderson Cooper vs. Star Jones

May I be the first to say, TEAM ANDERSON FOREVER. In anything. If Anderson Cooper jumped off a bridge, I would be hurtling down along side, screaming his name, and that's the sad truth. But Star Jones was also way off the cuff on this one, saying Cooper only came out to boost rating. Then Anderson called in the mommy power and said his mother, Gloria Vanderbilt, of like ...THE Vanderbilts, had no idea who Star Jones even was. Case Closed. Anderson - 1, Star Jones - 0.

Drake Bell vs. Justin Bieber

In the one scenario where Justin Bieber actually came out looking like the less crazy one, Drake Bell made fun of the Bieb's songwriting talent, or lack thereof. When, to the surprise of no one, an onslaught of angry Beliebers came to Justin's defense, Drake launched a Twitter rant. I hate to say this, but come on Drake, pick on someone your own age, please.
