Vanness Wu, member of Taiwan's popular boy band F4, joined in a rehearsal for Hong Kong singer-actress Gigi Leung's upcoming solo concert on Wednesday, reported the Hong Kong-based publication Tungstar.

Invited as a performing guest, Vanness will dance with Gigi during the song "My Kingdom" and sing another solo of his own.

"We have to hurry up because we only have two days for practice," Gigi said.

Venness is like a Christmas gift to me because he flew all the way from the United States to Hong Kong especially for the concert, the entertainer was quoted as saying.

Gigi's concert will be held on December 21.
