Michelle Obama and David Beckham have taken to the football pitch to practise their penalties ahead of the Olympic Games.

The First Lady was hosting an event at the US Embassy for around 1,000 children to urge youngsters to stay healthy and "believe" in themselves.

After telling the crowd she was "so excited" to be there, she turned to the US athletes standing behind her, and said: "You're not born an Olympian, right?

"In fact, many of them started out just like you, just playing. What they did do is they stuck with it. When they got tired and frustrated or fell short, they didn't give up."

She then took part in a series of activities, including football with the former Manchester United player, with both of them scoring goals.
