Former 'ER' star Ming-Na is a mother again. The 41-year-old actress has given birth to her second child, a boy, in Santa Monica, California, People magazine reported on Thursday.

"Mother and baby are doing great," her husband Eric Zee told People.

Cooper Dominic Zee, born Wednesday afternoon at St. John's Hospital, weighing in at 8 pounds and 9 ounces, joins his four-year-old sister, Michaela.

Ming-Na, 41, played Dr. Deb Chen on "ER" and starred on NBC's short-lived drama "Inconceivable" this season, which was set in a fertility clinic. (The show has been pulled from NBC's schedule.)

After signing on to the show, she found out she was expecting.
"I threw them a curveball," the actress told People magazine last month. "You know, I'm such a Method actor!"
