Johnny Knoxville has walked down the aisle.

The Jackass star and girlfriend Naomi Nelson wed on Friday, a rep confirms to UsMagazine.com.

Knoxville, 39, popped the question with a 2.50 carat Edwardian engagement ring from L.A.'s Platt Boutique Jewelry.

"Naomi was drawn to this ring because it is unlike anything she had seen–feminine, delicate and detailed," jeweler Larry Platt said of the bling.

The couple welcomed son Rocko Akira Clapp in December. (Knoxville also has a teen daughter, Madison, with ex-wife Melanie Clapp).
