They're always just, like, walking around smiling and laughing together.
Tonight, at the VMAs, they performed their hit song "Señorita" together for the first time.

MTV had an audience cam on all the famous people watching the "almost kiss" and their reactions were dramatically priceless.
Her hand goes to her heart.

Taylor fanned herself and gradually sat down.
And Bebe Rexha started doing this weird clap-stomping thing.
