“Jackass” Star Johnny Knoxville Married Naomi Nelson

Jackass star Johnny Knoxville tied the knot with his girlfriend Naomi Nelson in a small ceremony last Friday.

Knoxville, 39, plopped down a fistful of dough on a 2.50 carat engagement ring for Nelson from Platt Boutique Jewelry only two days before walking down the aisle.

“Naomi was drawn to this ring because it is unlike anything she had seen–feminine, delicate and detailed,” says jeweler Larry Platt, who designed the sparkler.

This is the second marriage for Johnny, 39. He divorced Melanie Clapp in 2007 after 11 years of marriage. They have a teenage daughter, Madison. Knoxville began dating Nelson in 2008. The couple welcomed son Rocko Akira in December.
