'The Office's' Angela Kinsey Gives Birth

Fans of "The Office" can send congratulations and baby-friendly sunglasses and saxophones to Angela Kinsey.

The blonde actress and her husband, writer Warren Lieberstein, welcomed a baby girl into the family on Saturday, May 3, reports People.

Isabel Ruby Lieberstein weighed 6 lbs., 14 oz. at birth. The actress' mother Bertie and "Office" castmate Jenna Fischer were present at the hospital to greet the new arrival.

Kinsey, 36, and her husband had reportedly been trying to get pregnant for a while. The actress announced her happy new last November on her MySpace blog.

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

Kinsey plays uptight Dunder Mifflin accountant Angela Martin on NBC's "The Office." The actress is the sister-in-law of actor and co-executive producer/writer Paul Lieberstein, who is known as the rather glum Human Resources rep Toby Flenderson on the show, and of "The Office's" writer-executive producer Greg Daniels through her husband.

Warren Lieberstein has written for "All of Us" and "Carpoolers."
