She's not an actor, she's a pop star. The watch James Bond wears is often considered an integral part of his character, but the internal part of a pop star is dancing/singing, not some piece of software that was used for a segment for a couple of mere seconds. That'd be like accosting a Bond actor for not knowing the name brand of a pen he randomly picks up to scribble a note really quickly - eg, stupid. Give her shit for not knowing the name of a dance move, fine, but this spreadsheet thing? Chill.
