ET's special correspondent Cheryl Woodcock was among the guests at the Saturday nuptials between Heidi Montag and Spencer Pratt -- and she reveals the details from inside the ceremony!

Cheryl, who attended the nuptials with her daughter Skyler, says the ceremony was nothing short of "tasteful and elegant."

"The ceremony was based on trust, hope and love," she says. "You could really see that this young beautiful couple was truly in love, and their intentions today were to say their vows in front of God and their closest family and friends."

Heidi's father walked her down the aisle wearing a cowboy hat, which Cheryl learned was a request made by Heidi.

"He looked shockingly handsome and she looked stunningly beautiful," Cheryl enthuses about the couple, adding that Heidi's long, sparkling veil "took everyone's breath away."

Cheryl says the ceremony location was beautifully adorned with cream and white roses, while the bridesmaids wore one-shouldered, buttercup-yellow gowns. "The Hills" stars Brody Jenner and Audrina Patridge were also in attendance, Audrina wearing a strapless, navy blue mini-dress.

One of Heidi's bridesmaids was Spencer's sister, Stephanie Pratt, who is also a cast member on "The Hills."

Cheryl noted that as Stephanie made her way down the aisle, she mouthed the words "I love you" to her brother, who whispered them back to her.

Before Heidi made her way down the aisle, Spencer looked excited, smiling and dancing around as he awaited his big moment.

After the vows, it came time for Heidi to throw the bouquet -- and Cheryl says it was none other than "Laguna Beach" alum Kristin Cavallari who caught it!

Heidi and Spencer's wedding ceremony was followed by a reception at the Beverly Wilshire Hotel. The nuptials were captured by "The Hills" cameras, and will air on the hit MTV reality series.
