Joe Jonas recently appeared on a cooking show – but not everyone knew who he was.

He’s been putting in several appearances on TV shows recently, including Sonny With A Chance with ex girlfriend Demi Lovato and 90210, but we had to laugh at his Top Chef All-Stars appearance.

Most contestants were happy to see an actual Jonas Brother on set, but one guy didn’t know who he was.

“I had no idea who Joe Jonas was,” one contestant, Dale Talde, confessed. “I thought he might be a pastry chef?”

The challenge was to make the perfect midnight snack for kids.

“Hopefully what you make today will be fun for the kids,” Joe told the eager-yet-confused chefs. “Make it original. You can’t just show up with peanut butter and celery.”
