Splitsville! Johnny Knoxville and Wife Melanie!

Johnny Knoxville's rep confirms to Usmagazine.com that the Jackass star is calling it quits on his marriage. "They have been separated," Amanda Silverman, Knoxville's rep said.

Knoxville, 35, and his wife Melanie have been married since 1995, but rumors of infidelity reportedly have hurt the relationship. While filming The Dukes of Hazzard, there were wide-spread rumors that he was having an affair with co-star Jessica Simpson, although both parties have denied it.

According to one source, the blame should be put all on Knoxville. "How do you live knowing that your husband leads a separate life... and is sleeping with other women all the time? She deserves every penny if she is going to divorce him," the source said. As for if they will get divorced, an insider said, "I really don't know. They have been separated for a while. They just grew apart."

The couple has one daughter, Madison, 10.
