Jessica Biel and Cameron Diaz are going to be kept apart at the MTV Movie Awards on June 5th. The network is setting up all the stops to prevent a catfight between Justin Timberlake’s current and former dimepieces.

Cameron lost her temper at Prince’s Golden Globes after-party in January and had a furious argument with Justin after she saw him cozying up with the new “love of his life” Jessica shortly after their split.

Both actresses will be in the house to present and J.T has been nominated for Best Breakthrough Performance for his movie ‘Alpha Dog’.

“Everyone is determined to keep Cameron and Jessica far apart. It’s becoming a big deal because the girls both want separate arrival times. “Nobody knows who Cameron is going to bring, if anyone. But if Jessica walks in with Justin, Cameron will want to bring a date. If Jessica goes alone, Cameron will probably walk alone. It’s a mess,” a snitch tells Page Six.

“Cameron is used to being more high-profile than Jessica. But now that Jessica’s dating Justin, she has more leverage. Cameron’s looking a little unstable lately.”
