"Her name is Erin Kristine Ludwig," Ziering, 45, tells PEOPLE in an e-mail. "She's a nurse, we're planning a spring wedding and we've been together since Labor Day 09."
This will be the second marriage for Ziering, who played Steve on the hit show in the '90s and was a Dancing with the Stars celebrity dancer (with Cheryl Burke) on its fourth season. A 1997 first marriage, to model-actress Nikki Schieler Ziering, ended in divorce in 2002.
