Hong Kong superstar Eason Chan has become the first Chinese artist to perform at London's O2 Arena.

The singer sold out the arena within 20 minutes of tickets going on sale and crashed the venues servers.

Before the show Chan said he was surprised by the high demand in London but promised a show full of energy.

The performance was part of his popular "Duo Eason Chan" tour which kicked off in his hometown of Hong Kong on March 20.

The tour will take him to 35 cities in nine countries.

The 37-year-old has released more than 30 solo albums and is one of the best-selling Mandarin and Cantonese pop artists.

This was his second appearance on a London stage after performing at the Royal Albert Hall back in 2010.
