Heidi Montag is officially Mrs. Spencer Pratt.
The Hills stars got married in an early evening ceremony at the Westminster Presbyterian Church in Pasadena, Calif., on Saturday, PEOPLE has confirmed.
Montag, 22, and Pratt, 25, exchanged vows before about 200 guests, including Audrina Patridge, Kristin Cavallari, Brody Jenner and Frankie Delgado. The bride wore jewels from Neil Lane, including a pear-shaped diamond floral necklace with multiple diamond chains layered over it, diamond earrings and diamond hairpins, which she picked out the day before the nuptials. Pratt borrowed a pair of diamond cufflinks from the jeweler for the big day.
Early Saturday, the couple arrived at the church in a white Rolls Royce Phantom. Before the ceremony, an airplane flew overhead and wrote “Spencer loves Heidi” in the sky. Pratt, looking dapper in a black suit, smiled and signed autographs for fans outside the church.
Meanwhile, Montag posted multiple updates on Twitter throughout the day. “This is going to be the best day of my life,” she wrote at one point. “Thank you God for Spencer.” She also described her wedding dress as “amazing – like a swan princess.”
After the ceremony, the newlyweds emerged and kissed on the church steps. Wedding guests threw rose petals at the couple, who left for the reception in black Rolls Royce Phantom.
