Metallica drummer Lars Ulrich and his girlfriend, Gladiator star Connie Nielsen, are celebrating the birth of their first child together. The baby boy was born in New York earlier this week, but his name has yet to be announced.

New mom Nielsen says, "Everything is fine. He eats. He's wonderful. And we are extremely happy."

Ulrich has two sons from his marriage to American doctor Skylar Satenstein, Myles and Layne, who are eight and five years old respectively.

Nielsen has a teenage son - Sebastian, 16 - from a previous relationship.
