Multi-Olympic gold winner Guo Jingjing finally tied the knot with Kenneth Fok on Wednesday in Hong Kong.

Pictures of Guo in wedding dress were spreading online on the day when reports said the 31-year-old former diving queen and Fok, 33, had the marriage registration.

Guo retired in 2011 after she bagged four Olympic gold medals and eight world titles. Her romance with Kenneth Fok, eldest son of Hong Kong tycoon Timothy Fok, has kept her a headline both in and out of the diving pool since after the 2004 Athens Olympics.

It was also reported the marriage registration is only the prelude to a magnificent weddning celebration in which the guest list will read like a who's who of the sporting, business and entertainment world.
