Oops, she did it again! First, there was #muggate [1], and now Demi Lovato [2] is adorably confused about jeans. In a Q&A with a group of British school girls, for BBC Radio 1 [3], the "Confident" singer [4] totally got her words mixed again. It all started after she asked the girls she was driving home as part of the interview what they learned in school. "In health, we learned about inherited genes and stuff," one girl replies. Simple enough, but Demi thinks she's talking about jeans: "OK, that's good. Like hand-me-down clothing?" She immediately corrects herself but not before everyone has a good laugh. In her defense, she was concentrating on driving on the wrong side of the road!

Later the girls go deep asking Demi how much she's worth, if friend Iggy Azalea's backside is real, if she would ever date Nick Jonas [5], and even whether she would snog Nicki Minaj. Watch the video above to see the whole thing unfold, then take a look back at Demi's style evolution [6] and get inspired to go as her this Halloween. [7]
