'Sopranos' alum Jamie-Lynn Sigler expecting second son

July 28 (UPI) -- Former Sopranos star Jamie-Lynn Sigler is going to have a second son.

The 36-year-old actress enlisted husband Cutter Dykstra and 3-year-old son Beau Kyle to help announce she's pregnant with a baby boy.

"We are excited to announce, it's a...... video and edit by @donatiennela," she captioned a clip Friday of Dykstra pitching a ball filled with blue powder to Beau.

Sigler told fans this month that she and Dykstra, a 28-year-old former baseball player for the Washington Nationals, are expecting another child. She shared a photo July 18 of her five positive pregnancy tests.

"This is the actual pic I sent my husband this past Mother's Day while lying on the bathroom floor. I had just returned from Israel, was jet lagged, and didn't believe my eyes. So had to obviously be @Clearblue 5x over sure," the star wrote.

"We are SO excited to announce the #ClearblueConfirmed arrival of another little one in just a few short months," she added.

Sigler and Dykstra married in Palm Springs, Calif., in January after a three-year engagement. The actress went public with her 15-year battle with multiple sclerosis in an interview with People published just days later.

"Things are manageable now," she told the magazine. "It takes a fighting attitude to deal with all of this. This disease can absolutely take over your life if you let it."

Sigler is known for playing Meadow Soprano on The Sopranos, and has since appeared on Entourage, Ugly Betty and CSI: Cyber. She will next star in the movie Justice with Stephen Lang.
