Celebrate Mother's Day with two kids - that is the suggestion from netizens after home-grown singer Stefanie Sun posted a photo last week on Chinese micro-blogging platform Weibo. The picture showed the 38-year-old and Hong Kong actress Charlie Young, 42, cradling Young's twin sons. Sun and her husband, Dutch entrepreneur Nadim van der Ros, have a four-year-old son. Young is married to Singaporean Khoo Shao Tze.
