Keeley is dancing in her pants

SAUCY Upstairs Downstairs babe Keeley Hawes says she loves dancing around in just her pants.

The stunning actress, 36, is only ever seen in posh frocks and fur coats in the BBC1 drama.

But Keeley – who played Alex Drake in Ashes to Ashes – says she wears much less off screen!

Comparing herself to X-rated pop star Madonna the Brit beauty said: “I love Madonna. I’m a bit of a fan, and she’s always dancing in her pants - so we’d have something in common!”

Keeley famously played a rug-munching lesbian in 2002 sauce-fest Tipping The Velvet.

And the posh totty, married to her Spooks co-star Matthew Macfadyen, says she’s got a healthy appetite for nookie.

Asked how often she has sex, Keeley revealed: “It depends if my husband is away or not – er that doesn’t sound quite right!

“When we are together – quite a lot, actually!”
