Tom Arnold is once again a married man!

A rep for Arnold confirms that the comedian wed Ashley Groussman Saturday at a private beachfront home in Maui, Hawaii.

With about 100 guests that included Helen Hunt, Mike Myers and best man Dax Shepard, the affair was a "vintage Oriental style wedding," with a Buddhist monk standing by and an Asian menu, according to one attendee. After exchanging rings, the bride and groom -- he in a dark suit, she in a white dress -- chanted a Buddhist prayer. "It was very quiet and peaceful," the guest tells Us, adding that everyone posed with the happy couple for photos on the beach following the ceremony.

Held Friday, the rehearsal dinner went down at Mala Wailea restaurant at the Wailea Marriot in Maui. The entertainment? Karaoke! "Tom was leading the way!" the insider tells Us.

This is the fourth marriage for Arnold, 50, who was most famously married to Roseanne Barr in the early 90s.
