Heidi Montag, who has chronicled her rocky relationship with Spencer Pratt on MTV's smash reality series The Hills, has married Pratt at a resort just outside Cabo San Lucas. Last season, the series ended in a cliffhanger–now apparently resolved–as to whether the couple was actually engaged. The relationship between Montag, 22, and Pratt, 25, set off an explosive feud with former buddy Lauren Conrad. (Photo: WENN)
