Swaggering EastEnders star Danny Dyer was pictured naked by a starstruck 21-year-old while he spent the night with her behind his loyal partner's back.

The bad boy actor, who plays Queen Vic landlord Mick Carter, homed in on the young brunette at a club and they went back to her bedroom.

The pair swapped numbers after their night together a month ago and the student hoped Dyer, 36, would contact her again – but he never did.

She showed the mobile pictures to a pal and they have since been shown to the Sunday Mirror.

Dyer has previously admitted to betraying girlfriend Joanne Mas – the mother of his three children – but recently described her as his "f****** rock".

Just weeks before his night with the student, he was pictured at Joanne’s side at the premiere of new film The Hooligan Factory.

They have been together 19 years.

But all that was forgotten as Dyer spotted the student on a night out with pals last month.

A friend close to the girl – who did not want to be named – said: "Danny clearly fancied her.

"Of course she recognised him straight away too.

"And you don't expect to see somebody who has been in so many films and on TV in your local nightclub.

"He got chatting to her and was very flirty – and she was pretty flattered that someone famous was showing an interest.

"She certainly fancied him too, and found him very charming and likeable.

"She wasn't sure whether he had a partner when they started talking, but the conversation flowed really easily between them both and kept on almost all night.

"They had a few drinks and when it got late they decided to leave together.

"She was a bit embarrassed afterwards, and told her friends that he had gone back with her.

"It really isn't the sort of thing that she would normally do, and she certainly wouldn't have taken pictures with a man, but was a bit starstruck and carried away in the moment.

"She couldn't believe she ended up in bed with someone like Danny Dyer as he could have had the pick of anyone.

"But she was disappointed at not hearing from him afterwards.

"She couldn't help sharing what had happened with me and other close friends.

"Some didn't believe her until she showed them the pictures.

"At the time she had no idea Danny was in a relationship but now she knows he is she realises it will be never anything other than a one night stand."
