Ian Ziering -- a.k.a. Steve Sanders on the original Beverly Hills 90210 -- is getting married!

The Dancing with the Stars alum, 45, announced the news in thoroughly modern fashion: via Facebook! The actor recently changed his status from "in a relationship" to "engaged." The bride-to-be is Erin Kristine Ludwig.

Will Ian and his love last as long as these couples?

On January 8, Ziering posted a happy photo of him having a champagne toast with Ludwig -- who wears what appears to be an engagement ring . "So in love with my love am I," ZIering gushed in a caption below.

Ludwig's own Facebook profile photo is another romantic shot of her with Ziering.

It's the second marriage for the TV star, who divorced first wife Nikki Schieler after five years in 2002.
