Five months after eloping in Mexico, Hills stars Heidi Montag and Spencer Pratt have said "I do" again.

Montag, 22, and Pratt, 25, wed in front of more than 200 guests Saturday at 4 p.m. at the Westminster Presbyterian Church in Pasadena, Calif., Usmagazine.com has confirmed. (A skywriter above the church wrote "Spencer Loves Heidi" numerous times in the clouds before the ceremony.)

Montag -- who was draped in close to $1.2 million in Neil Lane jewels -- wore a custom-made, $19,000 Monique Lhuillier dress. Her father walked her down the aisle.

Her sister, Holly, served as maid of honor. Pratt's sister, Stephanie, was also a bridesmaid in the ceremony.

Pratt wore an Ermenegildo Zegna suit, as did all of his groomsmen.

His niece, Ava, was the flower girl.

Both Pratt and Montag didn't shed any tears during the ceremony, a guest tells Us, They also didn't say their own vows; the minister did.

In addition to Pratt's family, all four of Montag's parents were present - including her mother, Darlene Egelhof, who initially opposed the couple eloping in Mexico last November.

Lauren Conrad, who initially said she would not attend, had a change of heart and showed up, along with Brody Jenner and girlfriend Jayde Nicole, Audrina Patridge, Frankie Delgado and Lauren "Lo" Bosworth. The ceremony was filmed for their MTV show.

Music producers David Foster and Cathy Dennis -- who worked with Montag and also produced Katy Perry's "I Kissed a Girl" -- were also present.

"This is going to be the best day of my life," Montag wrote on her Twitter page. "Thank you God for Spencer." She also said her wedding dress was "amazing - like a swan princess."

On Friday, the couple held a rehearsal dinner at Wolfgang Puck's Beverly Hills hotspot, Cut.

Their wedding Saturday was wholly different from the casual ceremony they had in Cabo San Lucas, Mexico, last November.

Pratt said it was "totally spur of the moment" when he and Montag exchanged vows with $8 rings they picked up on their trip.

Still, Montag told Us, "The minute we said our vows, I couldn't stop crying."

Outraged that they secretly eloped, Montag's mother told Us Weekly at the time that she gave their marriage "six months."

I thought they were done filming the current season. I was only half watching Letterman the other night, but I think I heard Lauren say she's been done for a month and it's been great. And I thought this "season" was going to be half the episodes to get it over with or something. I could be pulling this out of my ass, though.

But a wedding would be a good season finale. Unless the finale is going to be "will they stay together or break up" because of all the problems they've been having.
