David Beckham made a lot of women happy when he posed in just his underwear for Emporio Armani billboards last December. His mother, alas, was not one of them, People.com reports.

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