Heidi Montag and Spencer Pratt
Rumor has it these two plan to get hitched in front of The Hills' cameras for the series finale. Let's check the Speidi relationship scorecard: In December 2007, they broke off an engagement. Less than a year later, the two eloped to Mexico after one too many shots of tequila. Once it was determined their wedding wasn't legally binding, the two couldn't gather the nerve to seal the deal at the courthouse. Sounds like the two have a long future ahead of them.
