David Beckham may have offended a very important fan — his mom — when he posed in just his underwear for Emporio Armani billboards last December.

"When the photos came out, she was the first one to call me and say, 'What are you doing?'" Beckham, 32, told Jay Leno during the soccer star's appearance Tuesday on "The Tonight Show." "I had to try and explain it to her and it didn't go down that well," said Beckham.

When Leno flashed one of the steamy photos, however, the studio audience squealed with approval.

"Do you normally sit around the house like this?" asked Leno.

Beckham has lived in the same neighborhood as Leno since moving to Los Angeles to play for the Galaxy. The two men traded jokes Tuesday about driving themselves places and life with a constant paparazzi presence.

Beckham apologized for the paparazzi hanging around the neighborhood, but also said American celebrity photographers "have been kind to us" compared to those across the pond.
