Hong Kong actor-singer Ronald Cheng and his wife of over 13 years, Sammie Yu, are reportedly divorcing.

Both were spotted at Wan Chai Family Court on April 15, further fuelling rumours of separation after Sammie, 45, made a cryptic Instagram Story during her birthday in March where she wrote she was starting "a new chapter".

She posted a photo with only their two children, but no Ronald.

The former couple have also unfollowed each other on Instagram.
