Chris Lane joined Britney Spears onstage Friday night (March 31) for a very provocative and unusual performance. Let's just say, it was a one-of-a-kind moment for a country star.

Lane has been in Las Vegas preparing for the 2017 ACM Awards, and the "Fix" singer decided to spend his downtime on Friday evening taking in Spears' Piece of Me show, a residency she's been performing at the AXIS Auditorium at the Planet Hollywood Resort & Casino in Vegas. The top-selling Sin City extravaganza features Spears performing hits from across her entire career on a high-tech stage, with plenty of dancers and production excitement, and true to her always-daring stage shows, there's no shortage of sex and sizzle in the performance.

Spears brought Lane onstage during her performance of a song aptly titled "Freakshow," but the singer didn't join her for a duet. Instead, Lane ended up on his hands and knees, surrounded by Spears and her dancers decked out in revealing garb. Spears proceeded to push Lane around the stage on his hands and knees, with a leash around his neck and a little urging from a crop in a performance that Lane admits was a huge surprise even for him.

"When I woke up yesterday I had no idea my night was gonna go like this," he writes on Instagram to accompany the video, adding, "@britneyspears thanks for the spankin."

Lane is no stranger to pushing the boundaries of country music. His first single, "Fix," did just that, and managed to reach No. 1 despite cutting against the grain. He'll be hitting the road in June with Florida Georgia Line and Nelly on the Smooth Tour, which will feature select stadium dates with the Backstreet Boys, and while it's sure to be a hot show, we predict nobody will be leashed and spanked with at any of those tour stops.
