HOLLYWOOD, Calif. — Actress Angela Kinsey has given birth to a baby girl, People magazine reports.

The "Office" star and her husband Warren Lieberstein welcomed Isabel Ruby Lieberstein on Saturday. The couple's first child weighed 6 lbs., 14 oz.

"Mom and baby are doing great!" Kinsey's rep Tess Finkle tells People.

Kinsey, 36, and Lieberstein, 39, were married on June 18, 2000. The star's husband is a television writer and the brother of actor Paul Lieberstein, who portrays Toby Flenderson on "The Office."

Kinsey first announced her pregnancy in a MySpace blog last November.

"They say when you stop trying, that's when it happens — and that's how it went for us," the actress wrote.
