Gwyneth Paltrow, Jane Fonda, Sarah Silverman and Zoe Saldana reveal favorite sex positions

Some of Hollywood's most famous leading ladies have opened up about their bedroom secrets.

Gwyneth Paltrow, Jane Fonda, Sarah Silverman and Zoe Saldana were all quizzed about their sex lives in the new TV series, The Conversation With Amanda de Cadenet.

And the answers were surprisingly candid.

When asked about her favourite position, Gwyneth, who is married to Coldplay singer Chris Martin initially squealed and squirmed.

But she eventually answered: 'I'm down with all of them.'

Comedian Sarah Silverman, 41, who previously dated Jimmy Kimmel and is now in a relationship with Family Guy writer Alec Sulkin, also answered the very personal question.

'I do enjoy a good sound missionary-ing... and I like to be manhandled,' Sarah said.

Zoe Saldana
, 33, who was most recently linked to Bradley Cooper, said: 'I like missionary and I like being on my knees too. And I love being on top... I love doggy-style or standing up.'

Jane Fonda, 74, was equally forthcoming, saying: 'While I am quite flexible and I can kneel, it's not quite as comfortable for me as it used to be before I had a fake knee... [I like to be] either lying down or sitting up on a couch with him coming on to me, no pun intended.'

The show is hosted by British television personality and photographer Amanda de Cadenet and is executive produced by Demi Moore.

Amanda, 39, is well-connected in Hollywood circles and counts Demi as a close friend.

She was previously married to Duran Duran bassist John Taylor with whom she has a daughter named Atlanta

She married Strokes' guitarist Nick Valensi in 2006 and the LA based couple have twins.

Her show airs in the U.S. on Thursdays on the Lifetime channel.
