Actress Gwyneth Paltrow admits she misses her two children so much when she's on location, that she is often brought to tears.
"Some days you think, 'Oh my God. They're in the bath right now and I'm not there.' And I would cry in my trailer," says the star, pictured at Monday night's Iron Man 2 premiere.
Gwyneth is mum to daughter, Apple, five, and son, Moses, four - her two children with Coldplay frontman Chris Martin.
The actress recently revealed she has pulled out of her new movie role to be with her family.
"You just can't not be there. You just can't. They are just sop beautiful and hilarious and I don't wan to miss it. And I also want them know that I'm there for them," she says.
