Random Thought: Do professional singers randomly burst out into song when they get home?

Do Singers, like Katy Perry, burst out into song like people do in musicals.. Do people do that? Or are they ‘tired’ of singing after a long week’s worth of singing in the studio?

Well, since I don’t know Katy Perry’s phone number yet to ask her what she does in her off time, let’s see what Google has to say about singing at home like they do in musicals: Nothing. Nada.

I tried searching various variations of the question, but nothing useful came up!

Guess I’ll have to wait until She calls Me..
