Pop sensation Backstreet Boys will perform their first concert in Hong Kong at the AsiaWorld-Expo on Friday.

The show, part of the American pop quartet's Unbreakable World Tour 2008, follows the successful release of their sixth album "Unbreakable" last October.

The one-night only event is supposed to be a must see for lots of pop fans.

The group arrived in Hong Kong on Thursday and was welcomed by their enthusiastic fans at the airport.

The boy band, now with Brian Littrell, Howie Dorough, A.J. McLean and Nick Carter, had already toured Malaysia, Australia, Philippine, Indonesia. They will also perform in Tokyo, Seoul as well as Hangzhou, capital of east China's Zhejiang Province on March 4.

The former five-member group was down to a quartet as co-founder Kevin Richardson left the group in June 2006 to pursue other interests.
