— -- "Sopranos" star Drea De Matteo and Whitesnake bass player Michael Devin are engaged.

Even better, the big moment happened during a concert.

The band was being introduced -- and as it's announced that Devin "is going to do something very special."

"I fell in love with a very beautiful woman," he says. "I want to embarrass her as much as I can."

He invites the actress up to the stage and said, "I've been in love with you since the day I met you and I will for the rest of my life and I hope that you'll marry me."

She responds to his proposal and asks if he'll love her children forever, he says "yes."

She says, "I'm gonna marry this m-------."

The band then performs "Is This Love."

Devin posted to Istagram, "Big Huge Thank You for all the Birthday wishes... And for all the blessings on my engagement to this kitty cat ... Much appreciated!"
