Sheridan Smith and Gok Wan are in high spirits as they arrive at Cafe de Paris in London to host charity evening West End Bares.

Pretty actress Sheridan rocks a sexy black dress and lets Gok cop a feel of her hot bod before the night begins.

Sheridan Smith naked? She laughs and looks shocked when Gok suggests she goes nude on stage for the Make A Difference Trust – a charity which raises money for HIV/Aids.

The West End star is encouraged to take her clothes off by the audience and soon gets into the spirit of the evening by collecting donations from the crowd.

Sheridan Smith starts to get naked with the help of Gok, who lifts her black dress up over her head. The actress reveals a saucy pair of suspenders as her frock comes off.

A topless but clearly nervous Sheridan leans towards Gok as she prepares to face the crowd.

Eventually the nearly naked Sheridan Smith bravely turns around, covering her boobs with her hands. The actress’s blonde locks blow into the air when she spins round with an excited look on her face.

Sheridan soon puts her dress back on and joins TV presenter Paul O’Grady to watch other volunteers dare to get naked for the charity.

Other celebrities at the event include Dancing On Ice star Chloe Madeley, who looks stunning in a short blue frock.

Despite helping to raise a large amount for the charity, Sheridan later Tweets her feelings towards her co-host Gok.

‘I will never forgive @therealgokwan for making me flash my fat arse & belly in public but jus found out we raised £35,000 for @MADTrust!! :D,’ the actress writes on Twitter.
