David Beckham has hit back at claims he used a body double for his latest sexy advert for his H&M underwear line, insisting he never used a “bum double”.

Rumours were sparked after eagle eyed fans spotted what appeared to be a stand in model for golden balls as he filmed the Guy Ritchie directed advert in Los Angeles last year.

In the ad the father-of-four races through people’s back gardens in his form fitting underwear, showing off his buff and tattooed body.

Speaking on French TV show Grande Journal about his recent move to Parisian club, Paris Saint Germain, he denied rumours he’d used a model for his body shots.

“No I can say the crotch is mine and the backside is mine as well,” he insisted. “I heard this the other day. Someone said that I had a stand-in for my bum, but no, I can confirm that’s my bum.”

Well, we’re glad you’ve cleared that up for us David!

You’d think the footballer might feel embarrassed about the attention on his undies, but the star admitted he’d loved making the advert.

“It’s been great working with Guy,” he replied when asked by the Associated Press if he’d enjoyed the shoot.

“He’s one of my favourite directors, and also a friend, so it was amazing to work with him on my new Bodywear commercial for H&M.”

While we might all enjoy looking at Becks in his kegs, the star claims he’s still not used to seeing his bulge up in lights.

“No matter how many campaigns I do with H&M, I will never get used to seeing myself on billboards,” he confessed. “It’s always a surprise to me when I see them. I’m lucky to work with such great photographers and stylists, so the images are always the best they can be.”
