孙燕姿在香港继续的亚洲巡演

Pop queen Stefanie Sun continues her Asian tour, and in Hong Kong she got a surprising birthday gift from a special guest.

Singaporean singer Stefanie Sun brings her "Kepler World Tour" to Hong Kong on Thursday. She kicks off the show with a string of hit songs such as "Cloudy Day," "Dash" and "Greenlight." Sun just turned 36 on Wednesday. Special guest Jacky Cheung surprises her with a birthday cake on stage that leaves her speechless.

Accepting the cake and the well wishes from the concert goers, she goes on to perform one of Cheung's classic ballads with the pop star.

The tour that kicked off in Taipei earlier this year has taken Sun halfway around Asia.
