The 48-year-old actor and his wife, Kim Painter, welcomed their third baby, a daughter named Nixie Barbara Lowe, on Friday, March 18, Chad confirmed to People.

“She came a little early, but she’s small and mighty,” Rob Lowe's younger brother told the entertainment news outlet. “All is well.”

According to Chad and Kim, Nixie's name references the water sprites of German folklore. "[It] seemed like a good fit because we’re both avid surfers — my wife more so than me — and are involved in the Waterkeeper Alliance,” the ER star said. Her middle name, Barbara, honors Chad’s late mother, Barbara Lynn Wilson.
