Zoe Saldana has revealed her favourite sex positions.

The 'Star Trek' actress - who recently split from Bradley Cooper - enjoys making love in a variety of ways but she finds '' doggy-style'' and sex standing up most satisfying.

She revealed: ''I like missionary and I like being on my knees too. And I love being on top ... I love doggy-style or standing up.''

Zoe, 33, was one of several stars quizzed about their sex lives on new Lifetime TV show 'The Conversation With Amanda De Cadenet'.

Other celebrities to lift the lid on their bedroom activities include Gwyneth Paltrow, Jane Fonda and comedienne Sarah Silverman.

Jane, 74, told Amanda - who is married to Strokes guitarist Nick Valensi - her positions have been limited by a fake knee she had fitted but she still enjoys an active sex life.

She said: ''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.''

Gwyneth, 39, was a little more coy on her sex life with husband Chris Martin, only saying she is ''down with all of them''.

Sarah - who previously dated Jimmy Kimmel and is now romancing 'Family Guy' writer Alec Sulkin - admitted she likes to be ''manhandled'' in bed.

The 41-year-old comic said: ''I do enjoy a good sound missionary-ing ... and I like to be manhandled.''
