LOS ANGELES — Noah Wyle and his wife welcomed a baby girl last week.

Actress Sara Wells gave birth to Frances Harper Wyle on Monday, the actor’s spokeswoman said.

Mother and daughter are doing well, and Wyle was “over the moon.”

Wyle and Wells married last summer at his Santa Barbara, California, ranch. Wyle has a son and daughter from his first marriage, to Tracy Warbin.

Wyle, who gained fame in “ER,” stars in TNT’s “Falling Skies,” which begins its fifth and final season Sunday.
