London, Feb : David Beckham is fuming after a spoof TV ad of a Viagra-type sex drug started making the rounds in China.

The 30-second dubbed clip has used a past footage of the Posh and Becks, in which Goldenballs is heard saying that the drug-called "USA Selikon" capsules- are his "secret weapon".

"Want to know how I can keep being strong and running on the football field? USA Selikon capsules help me a lot. It's also the secret weapon with which I can satisfy Victoria," the Daily Star quoted the voice, with Beckham's face on screen as saying.

A source has revealed that Beckham, 33, is angry over the ad targeting his sexuality.

"He doesn't find it funny. David's fair game and can take a bit of a ribbing in the name of comedy," said the source.

The source added: "But to poke fun at his sexual prowess to plug a product is overstepping the mark."

But, according to a sales manager for the drug maker, government authorities in China have approved the ad.

Spokesman for the ex-England captain said that footballer was aware of the video, but declined to comment further. (ANI)
