But has the gorgeous Girls Aloud singer gone under the knife?

Wearing a sexy strapless dress, with platinum blonde locks, an almost unrecognisable Sarah Harding looked every inch the buxom 50s pin-up on a recent night out in Mayfair.

But the question on everyone’s lips was whether or not the impressively busty singer has gone under the knife.

Back in March, Sarah, 29, admitted she wouldn’t rule out a boob job, saying: Sometimes you need something to refill them a bit, so yes, I’d definitely consider it.’

Although Sarah’s reps deny she’s had any work done, Harley Streetsurgeon Dr Aamer Khan tells Now he believes she may well have had a boob job and facial fillers to achieve her femme fatale’ look.

It looks like she’s had quite a bit done,’ he says.

She’s got a very unlined forehead, typical of Botox, and she may have had cheek fillers because the shape of her eyes has changed.

‘Her chest just looks overcrowded and it’s likely she’s had large implants to bring her chest right up – you can see the tops of the domes.’

A source tells Now that Sarah, who has already got a new presenting job on Sky, hopes her glam new look will lead to more acting work.

After St Trinian’s 2, Sarah fell in love with acting,’ says an insider.

She’s desperate to break into Hollywood and Cheryl Cole has promised to introduce her to any agents she meets while out there.

Sarah knows she’s got no chance in LA unless she gets rid of her “caner” image.

‘Americans hate that “messed-up ladette” thing, so she wants to revamp herself as feminine and ladylike.’
