Heidi Montag Says Mother's Allegations Spencer Drugged Her Before Wedding Are 'Disappointing'

'The decision to marry Spencer was very much mine,' 'Hills' star tells UsMagazine.com.

Heidi Montag has denied claims made by her mother that then-boyfriend Spencer Pratt drugged her preceding her decision to marry him last month in Mexico, according to UsMagazine.com. Montag's denial comes the same day Pratt responded to the allegations about the impromptu marriage.

"I want to make it very clear to family, friends and fans that the decision to marry Spencer was very much mine," Montag said. "It was a beautiful day, and I've never been happier. For someone who wasn't even there to suggest otherwise is extremely disappointing."

Heidi's mother, Darlene Egelhoff, gives the marriage six months and admits to being disappointed in her daughter for choosing to marry her "Hills" co-star. "Spencer has tried to cut everyone out of her life," Egelhoff told Us. "I've been honest with Heidi, and it's caused our relationship to decline. I'm more devastated about that than the marriage, because I'm confident the marriage won't work out."

Heidi said she hopes that once the wedding airs on "The Hills," everyone will see that their love is real and that they're in it for the long haul. "I look forward to everyone seeing the footage of our time in Mexico on 'The Hills,' so they can see for themselves what a joyous occasion it was," she said.

Meanwhile, Pratt addressed the question of their marriage's legitimacy, saying he also has plans to make the marriage legal in the U.S. "I'm on it. In my mind, it's as legal as the ring on my finger," Pratt told Us. "But I wouldn't want everyone going around saying, 'It's not real.' "
