Heidi Montag said in Twitter updates from Pasadena, Calif., that she and fellow "The Hills" star Spencer Pratt have married for a second time.
"This is going to be the best day of my life," the actress wrote in one Twitter posting. "Thank you God for Spencer."
People.com said the MTV reality show stars did not invite any friends or family members to their Mexican wedding.
The couple's U.S. wedding on Saturday was preceded Friday night by a rehearsal dinner at the restaurant Cut that drew 40 guests as well as multiple camera crews, People.com said.
