Jessica Biel and Cameron Diaz will be kept apart at the upcoming MTV Movie Awards to prevent a feard cat-fight between the rivals.
Both screen beauties will be presenting awards and Justin Timberlake has been nominated for Best Breakthrough Performance for his movie 'Alpha Dog'.
Justin is Cameron's ex and is now dating Jessica
Organizers are concerned that sparks could fly if the two girls paths cross.
An insider told the New York Post newspaper, "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".
Cameron lost her temper at Prince's Golden Globes after-party in January and had a furious row with Justin after she saw him flirting with Jessica shortly after they split up.
The source added, "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'.
'Charlie's Angels' star Cameron is however now dating magician Criss Angel.
