Jamie-Lynn Sigler introduces son Beau Kyle

(UPI) -- "Sopranos" star Jamie-Lynn Sigler welcomed baby boy Beau Kyle with her baseball-player fiancé Cutter Dykstra back in August.

But unlike enthusiastic Instagramming parents Josh Duhamel and Fergie, Sigler has kept Beau's social media presence to a minimum -- last month she shared a photo of his tiny hand.

Sigler and Dykstra finally shared photos of Beau in the latest issue of US Weekly, in which the 32-year-old actress discusses motherhood and her upcoming wedding.

"I get how they say you will never know what love is until you have a child," she said. "It's such an overwhelming feeling of responsibility, of love, of fear, of everything."
