Los Angeles - Gwyneth Paltrow has joked she is ''addicted to sex''.
The Iron Man 3 star - who is married to Coldplay frontman Chris Martin - joined close pal and comedienne Chelsea Handler for an interview on her talk show Chelsea Lately and was left squirming when the discussion turned to her bedroom antics.
Chelsea, 38, jested: "OK, let's talk about sex addiction ... I know that you're addicted to sex."
Red-faced Gwyneth responded: "Yes."
Asked to elaborate on her racy admission, the 40-year-old screen beauty joked: "Well, basically, I was a really normal person and then I started hanging out with you all the time and I saw how much fun you were having..."
A fake 41 year body
The seemingly sexually liberated actress is seen stripping down to sexy black lingerie in new movie Thanks For Sharing but Gwyneth, who turns 41 later this month, claims she isn't confident about her figure.
Brushing off compliments about her youthful looks, she said: "I'm a fake 41. I tape myself up everywhere."
The mother-of-two - who has daughter Apple, nine, and son Moses, seven, with Chris - then conceded she was "as excited as you can be about turning 41".
While she may be paranoid about turning a year older, Gwyneth is looking forward to receiving a birthday gift from spouse Chris, 36.
The star recalls that one of her favourite presents from the Princess of China rocker was a personal cooking lesson with celebrity chef Jamie Oliver, who taught her how to make a "gorgeous duck ragu".
