In case you weren't aware, Team Her (and the rest of the world), are just a little obsessed with Beyoncé.
The below video, posted to Instagram account 'Beylite', is almost too much.
It shows the star rehearsing Drunk In Love on stage, before her daughter Blue Ivy chimes in with the 'surfboard' lyric.
Beyoncé responds with a big smile, saying "hi, Blue Blue" to which the little one says Mommy... and the expression on the mother-of-one's face at hearing her baby girl is so lovely.
