Cameron Diaz and Jennifer Lopez can't seem to get along on their movie set of What To Expect When You're expecting. Is Cameron jealous that JLo's trying to get all the attention, and is JLo jealous of Cameron for playing the lead? Now Magazine says:
"Cam thinks J.Lo's a nightmare and gives movie stars a bad name: "She's even said that Jen should stick to her day job, meaning American Idol and singing. Jen's constantly taking mini-breaks from the set to see her twins. She demands to eat at specific times, no matter what. So at 10:15am on the dot, she stops work and has an assistant run over to her with a small protein and veg-based meal. It's driving Cameron crazy."
