Speidi Eloped Across The Border

On November 20, 2008, Heidi Montag defied her mom and ran away with Spencer Pratt to Mexico to elope, which was like watching a trainwreck. Her friends had also told her that Spencer was no good for her. But she was happy when she exchanged vows at the One & Only Palmilla Resort, outside Cabo San Lucas.
