Spencer Pratt and Heidi Montag not newlyweds?

Spencer Pratt and Heidi Montag aren't actually newlyweds , OK reports. It was revealed on the finale of their reality show that the pair have yet to legalize their quickie Mexican wedding.

Spencer and Heidi first eloped on Nov. 19 in a ceremony in Mexico.

On Monday night's season finale of The Hills, Heidi's mom told her sorta-son-law, "I know you manipulated and plotted this whole wedding. It's too fast, too much."

The pair got all the way to the point of actually saying their vows in front of Deputy Commissioner Donna Jones. In fact, Heidi managed to get all the way through hers before a suddenly cold-footed Spencer had a change of heart.

"I feel like we're doing something sneaky and shady," he told his tearful bride-to-be. "I just want to give you the wedding of your dreams that you have been talking about for three years."
