She's the yummy mummy that mortifies her teenage son but more than delights his hormone-raging friends.

And The Inbetweeners star Belinda Stewart-Wilson will soon be back in the boys affections again - especially if she dresses like this.

The actress, 40, posed for a number of very sexy shots for men's magazine Loaded in little more than her underwear.

In one she sits across a window sill in just a bra, knickers and towering black heels while in the other, her curves in a black lingerie set peek out from a black mac.

Belinda is best known as Polly McKenzie, more commonly known as 'Will's fit mum'.

And she will be back, this time on the big screen, in the Inbetweeners movie.

Speaking to Loaded, Belinda says the boys were very behaved towards her, nothing like they are on-screen.

The shoot and a behind-the-scenes look at the movie is in this month's exclusive Inbetweeners edition of Loaded, out now.

She said: 'Quite the opposite, actually. I remember on the first episode of the first series, James Buckley swore in front of me and looked horrified and said, "Oh, I’m so sorry, I didn’t realise you were in the room."

'I was absolutely horrified by that and said, "Please tell me you’re joking." It was an odd dynamic at the beginning. They were a lot younger and I was playing a parent so there was a lot of banter between them that they excluded us from. It got better though. By the end of the show they were just essentially showing off for us.'

The third and final series of the popular - and very rude - Channel 4 show came to an end in October last year.

But if the pubescent, disgusting and sometimes bordering on derogatory antics of Will (Simon Bird), Simon (Joe Thomas), Jay (James Buckley) and Neil (Blake Harrison) weren't enough for some fans, there's plenty more to come.

Due for release next month, the movie follows the four friends as they go on a lads' holiday to Greece after Simon gets dumped by Carlyi (Emily Head), the love of his life and much fun and games and embarrassing situations ensue.

The film sees the return of supporting cast members Greg Davies, who plays their headmaster Mr Gilbert and Emily Atack as Charlotte.
