"Studio 60" actress Amanda Peet has given birth to a baby girl with her husband, "Troy" screenwriter David Benioff, The New York Post reported.

Peet went into labor Wednesday instead of keeping plans to attend a Hollywood luncheon, the Post's Page Six reported, citing an unnamed friend of the star.

The source told the Post that Peet was rushed to a nearby hospital. Peet's representative confirmed the birth of the baby, but wouldn't give any other details.

Peet and Benioff married in September after a four-year relationship.

Since the fall, Peet has starred in the NBC dramedy "Studio 60 on the Sunset Strip," which takes place behind the scenes of a "Saturday Night Live" comedy sketch show and was created by "West Wing" mastermind Aaron Sorkin. Rumors of an imminent cancellation have dogged the show almost since its September premiere.

Peet also had roles in films including "Syriana," "Something's Gotta Give" and "The Whole Nine Yards."

In addition to "Troy," Benioff wrote the screenplay for the forthcoming movie "The Kite Runner," based on the best-selling novel by Khaled Hosseini.
