·Editor, Yahoo Entertainment

Lucy Liu proudly showed off her new baby boy Thursday on Instagram.

"Introducing the new little man in my life, my son Rockwell Lloyd Liu. In [love]," she captioned a photo of her cradling the newborn.

In case you didn't know the Elementary star was expecting, it's because the announcement was a surprise.

"I can confirm that Lucy Liu is the proud mother of Rockwell Lloyd Liu, brought into the world via gestational carrier," her rep told The Insider With Yahoo. "Mom and baby are healthy and happy."

Liu, 46, has said very little about her personal life in the past. However, she did talk about children in an interview with the U.K.'s Daily Mail in 2013. The newspaper noted that in the past she'd said she wanted children. "It just hasn't happened yet," she said when asked about motherhood at the time.

While Liu hasn't said much else on the subject, she's known for her work helping children as an ambassador of UNICEF.

Since her CBS drama doesn't return until Nov. 5., the Charlie's Angels actress will get to spend plenty of time bonding with her new son.
