Six-time Olympic champion Usain Bolt was 'floured' by the Jamaican youth team to celebrate his birthday while in Beijing.

The sprinter, who is preparing for the World Championships in China, was the victim of the Jamaican tradition after turning 28 years old this morning.

Bolt tweeted a picture of himself covered in flour, and added the caption: "Ni Hao from Beijing-China on my Birthday..Can u believe the youth them flour me? Only Jamaicans #GiveThanks #Blesssed."

The Championships will get underway on Saturday.
