'The Office's' Angela Kinsey Pregnant

Notify the Party Planning Committee. Angela Kinsey is expecting her own baby that she can dress up with sunglasses and a saxophone.

"The Office" blonde and her husband, writer Warren Lieberstein, are expecting a child together due in May, reports Us.

"She and her husband are very excited," confirms the star's rep.

A source tells the celebrity magazine that the couple has been trying for a baby a while.

Kinsey, 36, 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."
