Insults abound between K-Stew and J-Law, along with R-Patz and Liamsworth!

It’s no secret that Twilight and The Hunger Games are being pitted against each other, but now an ugly competition is brewing between the young stars, OK! mag reports.

A source says that Oscar-nominated star Jennifer Lawrence, 21, isn’t impressed with Kristen Stewart. Not only did she supposedly call the 21-year-old Twilight star “snooty,” but she’s also dissed her for not thoroughly doing her homework for her role as Bella.

“When I heard Kristen Stewart say, ‘I only read the first [Twilight book],’ I was like, ‘Oh, man,’” said Jennifer, according to sources. She apparently added: “I was like, for [The Hunger Games] book lovers I should probably read the books.”

“It’s like part of Jennifer really wants to overthrow Kristen as Hollywood’s young darling, and she’s more motivated now that their feud is pretty much out in the open,” Jennifer’s pal tells the mag.

So how does K-Stew feel about J-Law?

Apparently, she’s not impressed with Jen, either — starting with her mug!

K-Stew has called J-Law “plain,” admits one of K-Stew’s buds.

“The whole industry is saying Jennifer is the next Kristen and Kristen doesn’t like that, but Jennifer doesn’t like it either; she wants to be her own person,” her friend added.

As for Robert Pattinson, 25, and Liam Hemsworth, 22, — well, they’re hatin’ on each other, too!

“I’ve never met Pattinson,” Liamsworth said, while adding he doesn’t really care for the Brit’s advice. “What do you say to someone? ‘Your life’s gonna change.’ Okay. Thanks. Cool.”

But a source says that the testosterone tantrums between the two dudes is worse behind closed doors.

“Liam feels like Rob should move over and make room for him,” said an insider, “but Rob feels Liam is just this silly, brawny ‘himbo.’ And Liam thinks all Rob can do is portray a sickly looking vampire and that there’s more room in Hollywood for the handsome hunk type.”

Looks like all four of them having been drinking too much haterade! Say whaaat?!!!
