Cate Blanchett has joked that Brad Pitt and Angelina Jolie are so in love it is"disgusting."

The actress - who stars alongside Brad in The Curious Case of Benjamin Button - says that seeing them so loved-up day after day on set was simply too nauseating to bear.

Cate tells The Telegraph, "To see how in love with Angelina he is, it was really quite disgusting. Awful in fact. "

She chuckles, "It's in my contract now: I won't ever work with him again."

Jokes aside, Cate also says that their main topic of conversation on set was about skin moisturisers because of the prosthetics involved in their ageing characters.
