The holidays are a time to celebrate goodwill for all human kind. And that’s cool and all, but it gets sort of old after a while. So now let’s take a minute and take a look at all famous folks who didn’t get the peace and harmony memo! We’ve assembled our list of the top 20 most brutal celebrity beat-downs of 2012. Join us in a chant of “Fight fight fight!” and check it out!

20. Rita Ora vs. Rob Kardashian: Rita Whora’s Revenge

Rob Kardashian didn’t handle his heartbreak all that great following his split with Rita Ora. Instead of posting passive aggressive Facebook statuses like the rest of us, he went on an all-out Twitter assault against his former flame, claiming that she cheated on him with 20 dudes, and coining the obvious pun, “Rita Whora,” which became a trending topic soon after. #Revenge? #SmallVictories

18. Michael Lohan vs. Rosie O’Donnell: No One Puts Lilo In A Corner!

It’s about to get loud! Michael Lohan fired back at Rosie O’Donnell’s not-so-happy reactions to Lindsay Lohan getting cast as Elizabeth Taylor. “I don’t think she’s right for the role and I don’t think she’s capable at this point to portray that character,” she said, before adding that the last good thing she made was when she was 16. “Who the hell is Rosie O’Donnell to judge anyone, especially Lindsay, who has far more talent than Rosie ever had?,” Mike shot back. Well, we saw Liz & Dick, and it turns out Rosie is a pretty good judge…

Just two weeks earlier he decked a paparazzo while picking up his marriage license.

Everyone knows you are NOT supposed to take kids there,” she railed. “She’s the biggest a–hole in the world,” the Tan Mom fired back. “She’s fake, she’s fat, her t–s are fake, she’s disgusting.”

9. Paris Jackson vs. Every Jackson Ever: Jackson Family Battle Royale

We’ll be honest: We never really got this whole controversy over who gets conservator rights for the children of Michael Jackson. We really tried to break it down for you, but it just made our heads spin. But there were a hell of a lot of Jacksons involved, so it deserves to be included!
