Jamie-Lynn Sigler and her fiance Cutter Dykstra are expecting their first child together, her rep confirms.

"She couldn't be more excited!" a source reveals to People.

The Sopranos actress and her baseball player beau recently announced their engagement on Twitter after a year of dating, so 2013 is shaping up to be an eventful time for the couple!

"Jamie can't wait to be a mom," the source adds.

No wedding date has been set, and the pair have yet to comment on whether their nuptials will take place before or after the birth. This will be the first child for both.

Congrats you two!
