A trio of western reality show stars are heading to Vietnam to perform in a joint concert in Hanoi's Quan Ngua Sporting Complex on June 16.
The concert is part of the annual H-Artistry event, sponsored by Hennessy.
The event requires its audience to register online to compete in one of four game shows for free tickets.
If they successfully manage to get on the shows, they'll still have to enter a lottery for the tickets.
The team includes American Idol winner and rock singer-song writer David Cook, British X Factor star and pop recording artist Alexandra Burke, and Australian Idol semi-finalist Thanh Bui.
All three artists competed over the airwaves in 2008.
David Cook, 29, rose to fame after winning the seventh season of the reality television show American Idol. Prior to Idol, he released an album entitled Analog Heart, and his post-Idol self-titled album, was released in November 2008.
Cook has since released three solo albums and won a few music awards, including the New Music Awards' Top 40 Male Artist of the Year in 2008 and 2009, and the Nashville Music Awards' Song of the Year in 2009.
Alexandra Burke, won the fifth season of X Factor and has since released her debut album, Overcome, in October 2009, which entered the UK Albums Chart at number one.
As of December 2010, Burke has sold over four million records in the UK alone.
The up-and-comer at the concert is Thanh Bui, an Australian-Vietnamese singer, songwriter and musician.
The 28-year-old singer was eliminated during the semi-final round of Australian Idol.
Prior to the reality contest, Bui toured with the boy-band North who made it onto the top-ten charts in Thailand, Indonesia, Malaysia and the Philippines.
Bui is the director and vocal coach at International Artist Academy and a successful songwriter.
He wrote the original soundtrack for the Vietnamese film De Mai tinh (Fool for love) as well as America's The Real World.
