Joe Jonas smiles autographs LAX

Just a few days after the Jonas Brothers band confirmed that they were done, Nick Jonas enjoyed a night out at the Sunset Marquis in West Hollywood. Don't worry, he's not pulling a Kylie Jenner -- as you may recall, the youngest bro in the band turned 21 back in September.

Nick has been working on his own music, and earlier this week the boys sat down with Good Morning America to explain why the band split up. "We're family first and that's always been our main priority and so honesty within what we do as a group was really important," Nick said. "I came to the table with the guysand shared my heart with them and my feelings. I said, 'Look, I feel like we've had some complications within the group for a long time [and] without addressing them I think this train will fall off the tracks ... It was a tough conversation. It was the first time we really had that real conversation."

In other news, before heading out on the town, Nick was stranded at Los Angeles International airport for a bit after a fatal shooting at Terminal 3. "Landed at LAX at to the news that there was a shooting in the terminal my plane was supposed to deplane at," he tweeted. "Currently waiting on the plane in a remote parking area. I am safe. Praying for the victims of this shooting." Glad he's ok ... but our hearts go out to those affected by the senseless act of violence.
