Congrats to The Office's Angela Kinsey, who gave birth to a baby girl Saturday afternoon.

Angela, 36, and her husband, TV writer Warren Lieberstein, welcomed their 6 lbs., 14 oz., daughter, Isabel Ruby Lieberstein. Also at the hospital? Angela's mom and her friend and Office castmate, Jenna Fischer. Don't you love when on-screen friends are also great friends off-screen?

Angela's rep told People, "Mom and baby are doing great!"

We're sure this baby will be just as adorable and comedic as her mom!
