It looks as though Brody Jenner might not just have some beef with Kim Kardashian these days, but his sisters Kendall and Kylie Jenner, too. Rumor has it that Brody is "fed up" with his sisters' antics and their overall bad behavior in the press.

According to Star Magazine, Brody tried to confront his dad Bruce and stepmother Kris Jenner about his younger sisters, but it looks as though his concerns fell on deaf ears as the girls are still "out of control."

According to the magazine, a source close to the Kardashian family says: "Brody laid it all out: the girls' hanging out with known drug users, the car accidents, all the attention-seeking online - he really tore Bruce and Kris apart and accused them of putting fame ahead of parenting."

The insider added that Brody feels that Khloe and Kim Kardashian are also responsible for Kylie and Kendall's behavior and that they apparently got an earful from him, too.

The source added, "Khloe is responsible for Kendall and Kylie hanging around guys like Chris Brown and Tyga, while Kim has made them obsessed with their looks. Brody feels like he's the only one who's got the girls' best interests at heart. He's worried sick."

So far no one from the Kardashian family has commented on the allegations on their social networking accounts.
