Girls Gone Wild founder Joe Francis had a big party at his Punta Mita, Mexico estate over the weekend -- but everyone kept their clothes on.

Tuxedo-clad Francis, 37, and girlfriend Christina McLarty, wearing a bridal gown, tied the knot in a civil ceremony. (See more pics at TMZ.)

Video entrepreneur Francis proposed to McLarty in June.

The one-time wild guy's inspiration to mellow out? His good pals Khloe Kardashian and Lamar Odom.

"Khloe and Lamar make an amazing couple," Francis, 37, told UsMagazine.com in August. "You see their energy together is real and true love," he adds.

"Just spending time with [Khloe and Lamar] is full of happiness and laughter," Francis told Us of the smitten pair. "My fiancee and I are the best of friends, just like Khloe and Lamar, and the next step for us to go down the aisle is only natural!"
