The Hills' Heidi Montag and Spencer Pratt had only two words to say to all the haters who've accused them of faking their romance for the cameras over the past three years: "I do." Five months after eloping to Mexico (for what turned out to be a nonbinding ceremony), the couple were finally married -- officially -- shortly after 5 p.m. on April 25 by the Rev. Twining F. Campbell at Westminster Presbyterian Church in Pasadena, Calif.

Before Heidi -- glowing in a Monique Lhuillier gown and wearing $1.2 million in Neil Lane diamonds -- walked down the aisle in front of about 200 friends and family members, Spencer, 25, told Life & Style the reason the couple decided to repeat their vows. It was, he revealed, so that Heidi, 23, could marry in front of her family -- including her mother, Darlene, her father, Bill, and her sister, Holly, who served as maid of honor. "I'm thrilled to finally be able to give Heidi the wedding she's always dreamed of," Spencer told Life & Style. And while Heidi's mom and Spencer haven't always seen eye to eye, Holly told Life & Style that, before the wedding, Darlene "had a heart-to-heart with Spencer and realized she needs to trust that Heidi knows what will make her happy."

Meanwhile, just five days before the wedding, Spencer's nemesis, Lauren Conrad, told Life & Style that while she'd been invited, she probably wouldn't attend. Apparently, she had a change of heart. Right before the ceremony began, Lauren entered the church through a side door and took a seat with fellow Hills cast members, including Audrina Patridge, Lo Bosworth, Brody Jenner and Frankie Delgado.

After the exchange of vows, Heidi changed into a sexy white dress and Gucci heels and joined her hubby and guests at Social Hollywood for a lavish reception.
