Did Katy Perry hit on Robert Pattinson behind Kristen Stewarts back? Did Angelina cheat on Brad? Did Jennifer Lawrence start a fight with PETA? All the answers after the jump.

Well, Katy DID crash Rob and Kristen’s night out at the Chateau Marmont on March 31st … but she did NOT get flirty with Edward behind Bella’s back. Reps for both parties are laughing off the In Touch story.

Did Angelina Jolie cheat on Brad Pitt?

Nope. Star magazine is reporting the couple recently had a big fight because Angie admitted she cheated on Brad a few years ago. A source close to the couple says the couple is happy and the story is 100% false.

Did Jennifer Lawrence start a fight with PETA?

She sure did. She made light of the squirrel skinning scene in Hunger Games saying she SHOULD say the squirrel wasn’t real but screw PETA. Did PETA get angry and send a “look at us” response? They sure did.

The organization’s president Ingrid Newkirk said in a statement Tuesday morning:

“She’s young and the plight of animals somehow hasn’t yet touched her heart. As Henry David Thoreau said, ‘The squirrel you kill in jest, dies in earnest.’”

Newkirk continued:

“When people kill animals, it is the animals who are ‘screwed,’ not PETA, and one day I hope she will try to make up for any pain she might cause any animal who did nothing but try to eke out a humble existence in nature.”
