'Sopranos' actress Jamie-Lynn Sigler and her fiance, baseball player Cutter Dykstra, are now first-time parents to a baby boy named Beau.

People confirmed that the couple's baby entered the world yesterday (Aug. 28).

Meanwhile, a rep for the new mama and papa both told Us Weekly: "Both mommy and baby are great!"

Said Sigler in the early stages of her pregnancy, "The first few months were not fun. I got hit pretty hard, but I feel fantastic now. It's the most natural thing your body can do. I have no part in anything that's happening with the baby. I'm just kind of a vessel, so it really is a miracle and it really is an exciting time."

The couple have been engaged since January of this year and announced their pregnancy in February.
