OneRepublic recently headlined the 'One Night Only Party' in New York City at Southern Hospitality BBQ, which is the restaurant chain owned by Justin Timberlake. The quartet entertained fans and a few celebrity guests with a live performance, and from the look of these pictures, the band looked like they were living the 'Good Life' while up onstage performing for the crowd.

The 'One Night Only Party With OneRepublic' was hosted by Neuro, the drink company that promises their beverages will help you "lose weight, sleep better and even invigorate your sex life," according to CBS. Ryan Tedder and the rest of the OneRepublic guys posed with an assortment of the colorful drinks and they looked like they were having a great time as they goofed off in front of the camera.

Justin Timberlake was also seen at the Neuro-sponsored party with OneRepublic. The 'SexyBack' singer was seen sitting with on-again, off-again girlfriend Jessica Biel, rock icon Elton John, and John's partner David Furnish. It looked like it would've been the perfect double date, except the couples also sat down to chat with Neuro owner Diana Jenkins.

Check out these pictures from OneRepublic's appearance at the 'One Night Only Party' sponsored by Neuro and let us know if you are excited about their upcoming album, slated for release in 2012.
