Shannen Doherty is days away from walking down the aisle! Life & Style can exclusively reveal that the 40-year-old has sent out save-the date notes for her marriage to photographer Kurt Iswarienko.

“It’s going to be on Oct. 15 in Malibu,” an insider reveals to Life & Style. And her Beverly Hills, 90210 fans won’t miss out on the nuptials! Shannen will be filming her wedding for a reality series that will premiere in January on WE.

After two previous marriages, Shannen clearly hasn’t soured on the institution. “I believe in marriage as a whole because my parents were married for 43 years, so I have the best example in the world of what marriage can be,” Shannen said.
