Jamie-Lynn Sigler is a mom

Jamie-Lynn Sigler and her fiance, Cutter Dykstra, are new parents to a baby boy.

The couple welcomed a son Wednesday afternoon. "Both mommy and baby are great!" Sigler's rep told Us Weekly. The newborn's name is Beau, according to People.

This is the first child for Sigler, 32, and 24-year-old baseball player Dykstra, who became engaged in January. They announcedtheir pregnancy the following month.

"We definitely thought it was going to be a slow relationship process and possibly an engagement -- I felt like it was coming -- so the baby definitely threw us for a loop," the actress said in April, reports People.

Sigler was previously married to her one-time manager A.J. DiScala. They split in 2005. Since then, she's been attached to fellow "Entourage" star Jerry Ferrara and New York Jets quarterback Mark Sanchez.

Sigler stars on the NBC series, "Guys With Kids."
