Aaron Kwok's ex Lynn Hung and husband Ken Kwok expecting baby

Lynn Hung may have given her husband Ken Kwok the best wedding anniversary present - a baby.

The 37-year-old model shared the good news in a Weibo post on Monday (Nov 6), and wrote: "It's my first time at work with my baby, what a wonderful feeling!"

Accompanying the post were two photos of Hung dressed in loose denim overalls.

She appears to be taking a break from modelling as she was seen styling a model for the sportswear line Devi Sport, a business she started with her husband in 2015.

The announcement comes after Hung was seen browsing parenting books in a Hong Kong bookstore last week with a baby bump.

Hung has made no secret of wanting to start a family with Kwok after the couple got hitched in a low-key ceremony last October.

In an interview, she said: "The most ideal is to have two. I'll have one first, and if I can cope and take good care of the child, I'll think of a second one."

Rumours of pregnancy emerged in February this year after they were spotted learning how to brew Chinese herbs at a famous traditional Chinese medicine clinic in Hong Kong.

Meanwhile, Hung's ex-boyfriend Aaron Kwok welcomed a baby girl in September with his wife Moka Fang.
