Taipei - Pop superstar Jay Chou and his girlfriend, model Hannah Quinlivan, have made an official online debut as a couple as he shared photos of them ahead of their wedding.

The two photos of Chou, 35, and Quinlivan, 21, were released through Weibo today, and he said: "It's time to share my joy with you."

Chou, who played two shows in Kuala Lumpur last weekend, said he "received the blessings of many fans" after the performances. "I saw some of you at the concert with your children - your whole families - sharing your joy with me, and I was very touched," he wrote.

In response, he decided to share photos of himself and his girlfriend, he said. The high-profile release of the photos was unusual for Chou, whose relationships have been quite low-key. His romance with pop star Jolin Tsai was never acknowledged even after it ended in 2005, with him leaving her for television host Patty Hou.

Although he has been linked to Quinlivan since 2011, they have never made a public appearance together. In June, he said he would be married before his 36th birthday in January, but did not name his bride.
