“I married the love of my life,” says Montag, 30, of Wilson, who is in medical sales.
The wedding was “magical and intimate,” she says, and held in Crested Butte, Colorado – the hometown of she and younger sister, Heidi Pratt, 27, who also starred in MTV’s reality hit.
Montag says she and Wilson’s first dance was to “Forever” by Ben Harper and she shared the father-daughter dance to “My Girl” with her dad, Bill Montag, and stepfather, Tim Egelholl (who also catered the event).
Pratt Tweeted her congratulations to her sister Sunday.
“Yesterday was the most beautiful wedding I could imagine!” she Tweeted. “Wishing you all the blessings and joy! Love you!”
Montag wasn’t the only Hills star to get hitched over the weekend: Lauren Conrad tied the knot with beau William Tell Saturday in California.
