They don't normally shy from the press, but Heidi Montag and Spencer Pratt quietly eloped in Mexico last Thursday, Nov. 20. "The minute we said our vows, I couldn't stop crying," Montag told Perez Hilton of the ceremony at the One & Only Palmilla Resort, just outside Cabo San Lucas. Montag, 22, and Pratt, 25, have chronicled their off-again, on-again (for good this time!) romance on The Hills – including a season cliffhanger about whether or not they were really engaged.Contacted by PEOPLE, Heidi's father, Bill Montag, had this to say of the couple's reported union: “I would be upset if she got married and didn’t invite me!" And if the report is true? "Then we just have to have another wedding here!,” he says.
By starting a relationship with the slick Pratt, Heidi Montag ultimately set off the well-known feud with former BFF Lauren Conrad. The couple is set to guest star on an episode of the CBS sitcom How I Met Your Mother in January.
