Dating back to the “Celebrity” video, Brad Paisley’s developed a running friendship with former “Star Trek” actor William Shatner, which created a weird moment in Brad’s household a year ago.

Shatner had a movie in the Nashville Film Festival, and when he went to Music City, Brad invited him out to visit at the farm. And William apparently had a pretty good time.

“One of the strangest things I’ve ever seen,” Brad told CultureMap.com. “I came home from the recording studio, and [he] was already over at the house, playing with my two-year-old son in the basement — with light sabers. I walked in to see my son and Captain Kirk, dueling with light sabers. I looked over at my wife, and asked, ‘What the hell kind of bizarre universe have I just walked into here?’”

Brad goes into William Shatner’s TV world — kinda, sorta — next month when he takes part in a taping for an upcoming CBS special in Las Vegas. He’s been added to the lineup for “ACM Presents: Brooks & Dunn — The Last Rodeo.” Other new additions to the special, which airs May 23, include Jason Aldean, Jennifer Hudson, Lady Antebellum, George Strait, Miranda Lambert, Sugarland and Taylor Swift.
