Giving the world a sneak peek of her bouncing baby boy, Jamie Lynn Sigler posted a photo of their interlocked hands on Saturday (August 31).

Along with the photo of little Beau Kyle, who she shares with fiancée Cutter Dykstra, the "Sopranos" star wrote, "We hold hands cuz we are besties."

On August 28th, the couple welcomed their addition to the family and mommy and baby are apparently doing very well.

Back in January, the proud new parents announced their engagement and just one month later, revealed her pregnancy.
