Yowza! Now THIS is the way to sell undies.

David Beckham, in all his glory, has stripped down to his skivvies to promote his new H&M bodywear line.

We can't help but notice that Becks is packing plenty of heat. Those muscles and tats are a combo we'd like to order daily.

Putting it in soccer terms ... Gooooooooaaal!

Speaking of soccer, the father of four has decided not to move his family back to Europe. Beckham turned down a chance to join the Paris Saint-Germain soccer team ... and plans to continue with The Galaxy here in the U.S.

The Galaxy is currently paying Beckham a reported base salary of $6.5 million.
