When it comes to showbiz catfights, they don't get any more A-list than this.

Word from the set of Cameron Diaz and Jennifer Lopez's new movie What To Expect When You're Expecting is that the pair can't stand each other.

And it's got to the point where the normally chilled-out Cameron, 39, has been sniping to anyone who'll listen about 42-year-old Jen's diva attitude.

An insider on set in Atlanta, Georgia, tells Now: ‘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 on American Idol'.

'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.'

Cameron, with Jennifer Lopez on set you will LOSE.

Reliable source.

Like half of the sources on ATRL.

I'm not surprised. I've read a lot of horror stories about JLo over the years. Idk why fans refuse to believe them. Those stories don't come out of nowhere.

I love JLO, but these "Diva" reports don't come out of nowhere, it's been like this since 2001. Unless, the media has been lying for all these years.

What's wrong with her taking a break to see her kids? Cam sounds pressed.

That was dumb. I think it has to do with her eating whenever she wants during filming.

Well ofc she is a diva. I don't think anyone could disagree with that. This isn't even that bad tho.

Hasbeen. Poor Cam.

It's annoying. They're probably working like 14-hour days. They wait and wait for hours for the next shot to be set up...only to have JLo **** it up b/c she can't eat 5 minutes later.

Cam's unbothered though. Her little $20M movie just crossed $200M: http://www.hollywoodreporter.com/new...teacher-228717

I wonder if Cameron remembers this interview:

She's the second highest paid actress.

Yeah, that ones a bit much but I mean, how else does she look so good? Eating at certain times.

I get where cam is coming from though. I'd be mad too. Especially if they were in the middle of shooting together. But she is the star soo. They always get what they want regardless.

This is tabloid bull. Both Jen & Cam's people have shot these rumors down.

& what makes it even funnier is that Jen & Cam don't have scenes together in the movie and were never on set at the same time

CLOSE THREAD.

They haven't, I use to be a big fan of Jenny but all the reports about her diva attitude turned me off, plus the music started to become less than good over the years to say the least. I don't believe everything I read but it seems quite plausible, she doesn't strike me as a humble person.

cameron is ugly

I just cant at the success of Bad Teacher, i never image a small budget R-Rate comedy can gross that much and more impressive that Cameron carried the movie on her own alone (Justin helped a bit with the ex work together buzz)

Oh right. It's an esemble cast.

End thread.

How does Cam lose with JLo sis?

I was referring to JLO getting what she wants on set and doing whatever the hell she pleases.
