We've found the person who rules Beyoncé and Jay-Z's home.
6-year-old Blue Ivy Carter.
She demonstrated her sass at the 2018 Grammy Awards. Seated in between her parents, Blue made a gesture that appeared to say "shut it down" or "calm down" at both Bey and Jay after they joined other audience members in clapping during American-Cuban pop singer Camila Cabello's speech about Dreamers and immigration reform.
Of course the moment went viral.
Jay-Z was nominated for eight Grammys at this year's ceremony but Blue Ivy continues to rule the world.
