It was a costumed affair for the party celebrating Dierks Bentley's No. 1 hit, 'Drunk on a Plane.' The singer, along with members of UMG, his record label's promo team, donned pilot hats and fake mustaches to help toast the recent success on Wednesday (Sept. 24) at Nashville's new hot spot, the Sutler.

'Drunk on a Plane,' written by Bentley, Josh Kear and Chris Tompkins, is the second No. 1 hit from the chart-topping 'Riser' record. The song, which tells the story of a man jilted at the altar, hits close to home for the Arizona native.

“I have never been jilted at the altar, but I have had a marriage proposal rejected ... all you can do is pray there’s a good return policy for the ring, get drunk and carry on,” Bentley notes.

“Whether I have the band with me on stage or it’s just me and my guitar, the fans love this song, and they catch on to the choruses immediately," he adds. "It’s a fun song, but when you really listen, there’s also an underlying lonesomeness, which is what makes it different that a lot of the other uptempo songs I’ve put out.”

The video for 'Drunk on a Plane' shows Bentley sporting a mustache and piloting a plane that turns into a party. He partnered with Funny or Die website creators Will Ferrell and Adam McKay to create the video, which marks the first time a country music video appeared on the comedic website.

Bentley is nominated for five CMA Awards, including Album of the Year for 'Riser' and Music Video of the Year and Single of the Year for 'Drunk on a Plane.'
