The Hills stars Heidi Montag and Spencer Pratt have walked down the aisle for real - marrying in a ceremony in Pasadena, California.

The couple staged a bogus ceremony in Cabo San Lucas, Mexico in November, but have now officially wed at the Westminster Presbyterian Church on Saturday.

After the ceremony the couple's guests, including Pete Wentz, Ashlee Simpson-Wentz, and singer Michael Buble, enjoyed a lavish reception at Los Angeles' Beverly Wilshire Hotel. And a spokesperson for the pair, who allowed the ceremony to be filmed for an episode of The Hills, confirmed the wedding was genuine.

The rep says, "Heidi Montag and Spencer Pratt joined hands in marriage. Dr. Twining F. Campbell served as pastor in front of 200 family and friends."

While Pratt's sister, Stephanie, one of Montag's bridesmaids, adds, "It was amazing. Heidi looked amazing. She was wearing a million dollars worth of diamonds over a strapless Monique Lhuillier dress. I was up there, and her back was towards me, so I don't know if she was crying. Everything worked out great."
