Demi Lovato has very different taste in food
Being interviewed should already come naturally to celebrities as they go through several of them in a week, even in a day. Of course, there are moments when they are not at their best when they are probably worrying about something huge, like mortgage payments, if they ever do have that, or some other personal issues.
We can only speculate that Demi Lovato was not 100% her usual self that fateful day in 2015 when she was interviewed by the German radio station NRJ. The host asked her what dish she likes the most. The host was talking about the dish as in the food—but Lovato took it to mean differently. She answered that her favorite dish was the mug because it was comfortable and held hot coffee or tea. The actress probably realized her answer was not on point, but this interview clip had already gone viral shortly after.
