Stacy Keibler married tech entrepreneur Jared Pobre in an intimate sunset ceremony on a beach in Mexico on Saturday, PEOPLE has exclusively learned.
"My happiness is indescribable!" Keibler, 34, tells PEOPLE. "Marriage is the ultimate bond of love and friendship. It means putting all your faith and trust into a person that you can't help but believe is your soul mate. Someone who has all of your best interests at heart; someone handpicked for you, to help you grow and be the best person that you can be. Jared is all of this for me."
Although the small wedding was a joyful surprise for family members vacationing with the couple, Keibler and Pobre have been quietly planning the low-key celebration for several months.
"We both felt strongly that our 'love day' should be intimately special, and that's exactly what it was," the couple tell PEOPLE in a statement. "It was a blend of romance, tranquility, natural beauty, bonding and overwhelming love."
Keibler, who amicably split from George Clooney early last summer, began dating Pobre, 39, in the fall. However, the two had been friends for over five years.
An Orange County native, Pobre is the CEO of Future Ads, a private interactive firm he started in 2001. By 2009, it was one of the fastest-growing interactive companies in the country.
This is the first marriage for both.
