Tom Arnold has married for the fourth time.

The comedian wed fiancee Ashley Groussman on Saturday at a private beachfront home in Hawaii. Helen Hunt and Mike Myers were among the 100 guests while Dax Shepard served as best man.

After exchanging rings, the bride - who was wearing a Claire Pettibone gown - and groom chanted a Buddhist prayer, before guests tucked into a feast of Asian food.

The couple met through mutual friends in April 2008 and got engaged at Tom’s 50th birthday party in March. “I’m the luckiest girl in the world!” Ashley said at the time.

Tom has regularly gushed about his new spouse, saying she has made him so happy. “I knew that if I could get Ashley to fall in love with me, I’d never have to worry about anything else as long as I lived,” he said.

Married three times before, Tom’s most famous union was to comedian Rosanne Barr. The two wed in 1990 before a high-profile divorce in 1994.
