Deciding to say their “I Do’s” on a spur-of-the-moment decision, Heidi Montag and Spencer Pratt tied the knot on Thursday (November 20) while on vacationing in Mexico over the past week.

The “Hills” co-star couple eloped in what’s being described as a small ceremony, held at the One & Only Palmilla Resort, just outside Cabo San Lucas.

According to insider reports, Spencer’s loving vows read: “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.”

Meanwhile, Heidi said to Spencer: “From the moment I met you, I knew I wanted to marry you. I never knew love existed like this. You have opened my eyes and shown me a new world. Every moment with you is magical and amazing. You are truly my prince charming and dream guy. I love you with all my heart and soul and promise to be the best wife to you every day for the rest of our lives. I can’t wait to see what life brings us. I will always be by your side!”

Getting congratulations from their “Hills” co-star, Audrina Patridge told OK! magazine: “I’m very excited for Heidi and Spencer and wish them a lifetime of happiness together.”
