Bourne Supremacy star Matt Damon and his wife Luciana have had a baby girl, his publicist has confirmed.
Damon's recent films include Syriana and The Brothers Grimm
Named Isabella, it is the couple's first child together, although Luciana has a seven-year-old daughter from a previous marriage.
Oscar-winner Damon, 35, married Luciana, 30, in a private ceremony in New York last December.
The actor's publicist, Jennifer Allen, said: "Mother and baby - everyone - is wonderful, fine".
Damon first rose to stardom in 1997 independent movie Good Will Hunting, which he co-wrote and starred in with his friend Ben Affleck.
The movie earned the pair an Oscar for best original screenplay.
After flops The Legend of Bagger Vance and All the Pretty Horses failed to excite fans Damon rebounded in 2002 with spy thriller The Bourne Identity.
Other recent successes include Ocean's Twelve and The Bourne Supremacy.
He is currently scheduled to star in sequels to both of those films.
