After walking the red carpet dressed in a religious robe, accompanied by a Pope look-a-like, she went all-out "Exorcist" while performing "Roman Holiday." She was literally climbing up walls, floating in the air and generally doing what possessed people will do.
Let's take a look back, shall we?
If you were possessed by an angry spirit named Roman, this is what you'd look like applying lipstick.
And the sight of a priest would definitely make you scurry up a wall.
When he tried to banish that demon, you'd start freaking out.
And try to escape from those shackles.
When you finally get free it'd be a super emotional moment.
So you might be tempted to grope a priest.
But the demon still isn't gone, so you'd pull an escape like this.
