Teen crush Joe Jonas might find himself getting pulled aside next time he tries to fly: the Jonas brother was stopped this week as he tried to bring a set of knives onto a flight from the Middle East to New York. He made it through one checkpoint before security in Abu Dhabi found a set of cheese-cutting knives he had mistakenly placed in his carry-on bag. His response was "Whoopsies!" his girlfriend, Twilight star Ashley Greene tells US Weekly. "Whoopsies doesn't cut it," she says. "We were going to get arrested!" Jonas was allowed to fly after the knives were stowed.
