Former boy bander Nick Jonas has entered into a controversial business investment now that his days with the Jonas Brothers are over. The 22-year-old is now an investor in a California-based alcohol delivery app called Saucey.

As a promotional stunt for the company, Jonas personally delivered booze and poured shots for several Saucey customers last Friday in West Hollywood. He also gave an acoustic performance of his hit song “Jealous” as those in attendance raised their glasses for him.

The Jonas Brothers were well-known in their early 2000s heyday for their squeaky clean image and promise rings, which symbolized their commitment to save sex until marriage. They even took part in an anti-drug school tour in 2005. But now that the former teen heartthrobs are full-fledged adults, some of them have opened up about experimenting with drugs.

In December 2012, Joe Jonas wrote an essay for New York Magazine in which he admitted to smoking pot for the first time at age 17 with fellow pop stars Miley Cyrus and Demi Lovato, but insisted they pressured him into doing it. He said that he rarely smokes weed anymore, but does “appreciate wine or a vodka-soda at the end of the day every once in a while.” However, Cyrus laughed off his story and said he would have smoked pot whether or not she was there.

"If you want to smoke weed, you're going to smoke weed," she told the New York Times. "There's nothing that two little girls are going to get you to do that you don't want to do. I thought maybe he was saying that like it was going to make him look badass. We were so young that it was actually like, ‘How did you get peer-pressured by me?’"

Joe also said he maintains a close friendship with fellow Disney kid Lovato, who has now been clean and sober for three years. He admitted regrets over not being able to be there for her in her time of need due to the image his band needed to uphold.

“I really got to know her and got to see the ins and outs of what she was struggling with, like drug abuse,” he said. “I felt like I needed to take care of her…because she needed help. I couldn‘t express any of that, of course, because I had a brand to protect.”
