Rachael Leigh Cook pregnant

Rachael Leigh Cook is pregnant with her first child.

The She's All That star is expecting husband Daniel Gillies' child and admits she has been struggling to hide her baby bump on the set of TV drama Perception.

The 33 year old tells UsMagazine.com, "I've been hiding my rapidly growing bump while shooting but this kiddo is vying for screen time. We clearly have a future actor on our hands."

The couple, who wed in 2004, also has another big pending arrival - they co-star in new TV movie Broken Kingdom, which Gillies has also directed.
