WATCH: Dame Helen Mirren on helium still sounds posher than us.

She’s so unbelievably… British.

Is Dame Helen Mirren the last person you’d ever expect to see sucking helium? Yes, yes she is.

But because the 69-year-old is the queen of doing completely out-of-character things, she did just that.

On The Tonight Show with Jimmy Fallon, Mirren was presented with a large helium balloon and proceeded to answer the rest of the interview in an incredibly high-pitched voice.

Fallon wanted to see if Mirren would still sound proper on helium. And yes, somehow, her impeccable British accent was still infinitely more posh than we’ll ever be.

All hail Queen Mirren.
