While filming Iron Man, Gwyneth Paltrow gave a little bit more than her body can handle and had to have surgery on her knee. She actually broke her knee, which truth be told, I didn't know was a possibility! OUCH!

"I broke my knee - because I'm a moron and I'm always bashing into things by accident. I've broken my toes 30 times. I don't know what's wrong with me. I bashed my knee, it really hurt."

The accident even caused a bust-up with director John Favreau, who was convinced she was exaggerating her pain:

"I kept exercising and running around in the movie. Then it really started to expand. In one scene I'm running away from Ironmonger - the bad Iron Man - and I said to John, "My knee is really hurting, I don't know how many times I can do this.' He was rolling his eyes, saying "you're fine'. But I went to the doctor and I had a fracture so bad they had to do surgery the next day. They put cement in there! So I felt very smug and he apologised. It still doesn't feel right. I had a nerve problem. My legs don't feel the same. Sometimes it happens with surgery. If I get a wax, one leg hurts more than the other."

And on a more personal note, Gwyneth spoke about how her children are two very different people.

"Apple is quite and imaginative. She will sit with her things and build houses and hotels for her dolls. Then my son will come in and thrash the hell out of anything she has been doing. If he can inflict pain, that's even better. But he's very sweet also. We call him our sensitive thug. It's a line from a Jay-Z song and it suits him perfectly."
