Hong Kong - Singer-actor Aaron Kwok's romance with model Lynn Xiong appears to be real, after the two were discovered by the Hong Kong media to have spent two nights together at his flat.

Kwok has been linked with China-born Xiong since 2006 but the two have never admitted being a couple and had largely avoided being photographed together.

But on the eve of her 28th birthday last Thursday, she let the paparazzi trail her as she drove from her flat to Kwok's condominium, just five minutes away.
