Lucy Liu Welcomes Son Rockwell Lloyd

Lucy Liu is a new mom!

The actress “is the proud mother of Rockwell Lloyd Liu, brought into the world via gestational carrier,” Liu’s rep confirms to PEOPLE. “Mom and baby are healthy and happy.”

The Elementary star, 46, shared a photo of her son via social media on Thursday, with the caption, “Introducing the new little man in my life, my son Rockwell Lloyd Liu. In [love]!”

While Rockwell is her first child, the actress has dedicated herself for years to helping children around the world, volunteering with UNICEF since 1994. Liu says being the daughter of two Chinese immigrants helped her to value what she had and made her want to help others.

“I felt like they really gave me an appreciation for the care and love we had,” she tells PEOPLE of her parents — who are now grandparents!
