Kevin Jonas boozes with brothers, wife in NYC

The Jonas Brothers rocker was seen ordering vodka and cranberry cocktails for himself and his wife Danielle at New York’s Empire Hotel rooftop bar after the premiere of Camp Rock 2: The Final Jam last week.

Jonas and his wife celebrated at the private party with his brothers, Nick and newly 21-year-old Joe, who gladly presented his ID to the bartender before collecting his Bud Light Lime, according to People magazine.

Nick recently insisted Kevin is still the same old guy — despite being a married man.

“He’s still the same old guy,” he said. “He just has a wife now, which is great! We like having her around.”

And for his part, Kevin recently said he isn’t worried his marriage will split the Jonas Brothers apart.

“Adding a new element to a rock band is always risky,” he said.

“But with Danielle, it’s been all good. And the brothers still find time to hang out, just the three of us, too.

“We spent the first two nights of the tour on Joe and Nick’s bus, and that was fun. They joke around with her all the time, just like she’s their sister.”
