Gwyneth Paltrow ''wouldn't mind'' having bigger boobs.

The 'Iron Man 3' actress is happy with her figure and looks, but if she had to change anything about her body she'd boost her boobs from a 34B size bra.

Speaking to Tatler magazine, she said: ''If I could change one thing? Nothing. Not because I think I'm beautiful, but I think I look the way I do for a reason. I wouldn't mind bigger boobs though.''

While she's happy with her physical features, the Hollywood star - who is married to Coldplay frontman Chris Martin - is convinced her nose is getting bigger.

When asked about her defining feature, she said: ''I tend to see only things I don't like. My eyes are quite small. And I'm paranoid my nose is growing.''

Gwyneth, 40, has now started doing aerial yoga - where practitioners are suspended from the ceiling and then carry out the Indian exercises - and she loves the fact she gets to hang upside down ''like a bat'' when she's doing it.

She explained: ''My teacher comes over with what looks like a portable hammock, attaches it to the ceiling and I just hang upside down like a bat for a bit.''
