Cameron Diaz loved having "big boobs" in 'What to Expect When You're Expecting'

Matthew said: "There was this one scene that got cut out - Cameron shows me her breasts! They were fake breasts of course, because her character was pregnant, so they made hers bigger.

"She was walking round with her shirt open all day on set though, loving her big boobs."

While Matthew loved working with Cameron, he admits he was overwhelmed when he saw how toned her physique was when they had to work on a dance scene together.

He told more! magazine: "Cameron is exactly like you'd expect. So lively and energetic - she always had a smile on her face and was cracking jokes left, right and centre. I had a great time with her.

"We do this dance scene in the movie and I learned the routine in Los Angeles and she learned it in New York, so we only had one day of rehearsal together.

"I didn't know what outfit she was going to be wearing though and when I saw it for the first time, I was like, 'Excuse me?!' Her body was just... wow. I did some sit-ups after that."
