Liu’s spokesperson said in a statement, “I can confirm that Lucy Liu is the proud mother of Rockwell Lloyd Liu, brought into the world via gestational carrier. Mom and baby are healthy and happy.”

The baby was delivered through a surrogate or gestational carrier. A surrogate or gestational carrier is a woman who bears the child of a mother who is not capable of carrying a child for some medical reasons like, having no uterus or removal of uterus due to cancer, according to the American Society for Reproductive Medicine (ASRM). The egg from the mother and the sperm from the father will undergo in vitro fertilization and then the fertilized egg is implanted in the surrogate mother’s womb.

In vitro fertilization is not limited to those who have problems with their uterus. Older women also need gestational carriers as they are more prone to miscarriages as they age. It is also possible that older women have chronic conditions that could pose health risks for them and for their baby.

The 46-year-old actress is just one of the few celebrities who sought a gestational carrier’s help to carry their baby. Other celebrity couples that have used this procedure to have a child include Sarah Jessica Parker and Matthew Broderick, Jimmy Fallon and wife Nancy, and Keith Urban and Nicole Kidman.

The actress has been actively working with children as a UNICEF volunteer. In an interview, she said she felt the kids’ appreciation for the “care and love” she had.

Liu is currently appearing in the crime drama Elementary, airing on WGN America.
