Johnny Knoxville Visits Ryan Dunn's Grave, Sends Emotional Tweet, Victoria Justice Dishes about Cool 'Fun Size' Co-Star

Hollywood wise guy Johnny Knoxville recently sent out an emotional tweet from the gravesite of his late "Jackass" co-star, Ryan Dunn. While Knoxville rarely shares his intimate feelings about his good buddy's passing away in a fatal car crash back in June 2011, the 41-year-old stuntman claims that he was happy to see so many people paying their respects at Dunn's grave. Such a somber graveyard visit comes right before the highly-anticipated release of the Halloween comedy "Fun Size," where Knoxville stars alongside Chelsea Handler and Nickelodeon actress Victoria Justice. In a recent interview promoting the new teen film, 19-year-old Justice refers to Knoxville as a really cool and down to earth guy.

Knoxville spent a lot of time with Dunn on the sets of the "Jackass" television show and films, where the duo became close friends and partners-in-crime. Dunn was killed in a drunken car crash in Pennsylvania in June 2011 at the age of 34. Knoxville gave a speech at Dunn's funeral and memorial service and wrote an online tribute, but spoke little of his friend's death after that. Last Wednesday (Oct. 17), Knoxville informed fans on Twitter that he had just gone to visit his pal's resting place:

@realjknoxville: "We just visited Ryan's grave out in Brecksville. Was glad to see he has had many people coming by to visit. Xoxo."

At the time of Dunn's passing, Knoxville sent out this emotional tweet (along with a number of other loving messages sent out by Dunn's "Jackass" family, including Bam Margera):

@realjknoxville: "Today I lost my brother Ryan Dunn.  My heart goes out to his family and his beloved Angie. RIP Ryan, I love you buddy."

On a lighter note, "Fun Size" (which follows the crazy Halloween night adventures of Wren, played by Justice) hits theaters Friday, Oct. 26. Justice tells Us Weekly magazine that the film will remind people of a classic teenage comedy from the 1980s - "[Fun Size is] in the realm of a John Hughes film. There are not that many films out there that are a great teen comedy that represent what teens are going through ... it has some heartwarming moments as well."

As for working alongside funnyman Knoxville, Justice insists, "[He is] one of the most down-to-earth guys I've ever met. He's so cool!"
