Montag, Pratt of 'Hills' marry in Calif.

PASADENA, Calif., April 26 (UPI) -- Heidi Montag said in Twitter updates from Pasadena, Calif., that she and fellow "The Hills" star Spencer Pratt have married for a second time.

People.com said Montag, 22, offered fans and friends routine updates on the social networking service regarding her most recent nuptials with her 25-year-old boyfriend.

"This is going to be the best day of my life," the actress wrote in one Twitter posting. "Thank you God for Spencer."

Nearly 200 guests were in attendance for the wedding ceremony at Westminster Presbyterian Church Saturday, a far cry from the couple's impromptu wedding ceremony in Mexico five months ago.

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.
