Say hello to MTV’s new Nick Lachey and Jessica Simpson.

Well, it’s official. Twiddle Dee and Twiddle Dum have gotten hitched. The Hills’ Heidi Montag and Spencer Pratt quietly eloped in Mexico last Thursday, November 20, the newlyweds report in this week’s issue of Us Weekly.

“The minute we said our vows, I couldn’t stop crying,” the bride says of the ceremony at the One & Only Palmilla Resort, outside Cabo San Lucas.

Here are the vows Spencer, 25, read to his 23-year-old wife:

Heidi, from the moment you came into my life, I knew my life would never be the same without you. You are the light in my life like the sun to the earth! Your loving warmth makes me want to be a better person. Being with you, I feel complete. I’m honored to even be able to call you my wife. You are the most amazing, loving and caring woman on this planet. I will love you forever and always.

(Insert gagging sounds here.)

Photos and details on the Pratts’ wedding will be available in the newest issue of Us Weekly, on newsstands Wednesday.
