Sport fans having their photos taken near the Olympic Park on Monday got the surprise of their lives when soccer star David Beckham unexpectedly dropped in.

For some, including 12-year-old Beckham superfan Christian Lewis and his mother Elaine, it was all just too much.

SOUNDBITE: Elaine Lewis, fan, saying (English):

"He's his hero. He just popped out and you know, David Beckham just showed his face and said do you mind if I come into your picture. He started crying and it's made me start crying. It was amazing."

Also given the Beckham surprise treatment were Linda Holgate and her children Emily and George.

SOUNDBITE: Linda Holgate, fan, saying (English):

"It was unbelievable, fantastic, I am still shaking. Just so exciting."

SOUNDBITE: David Beckham, soccer star, saying (English):

"I have kind of been popping my head in, surprising people, seeing their reactions and jumping in and taking pictures with them so it's been a good morning, it's been fun."

So, despite being left out of Team GB's football squad, it seems David Beckham still knows how to keep his fans very happy.
