"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."
