Johnny Knoxville is convinced veteran country icon WILLIE NELSON smokes marijuana in his trailer on the set of their movie The Dukes of Hazzard.

The Jackass funnyman has developed a strong fascination with the 71-year-old STARDUST singer - who's playing UNCLE JESSE in the remake of the hit 1970s TV series - but he's also suspicious about Nelson's private activities when the cameras stop rolling.

In an interview on website PAGESIX.COM, he quips, "Willie is the coolest guy on the planet. He's everything you want him to be and more.

"So far he hasn't been smoking any pot on the set, but I think he might be doing it in his trailer."
