Blue Ivy Carter knows best.
In a cute video that Beyonce's mom, Tina Knowles, posted on Instagram on Sunday, Tina daringly jumps off of the second story of a yacht, but not before getting a stern warning from her granddaughter.
"Do you know how to ... do you really know how to swim?," 4-year-old Blue asks Tina, clearly doubtful.
"She does," a man can be heard reassuring Blue, as another woman cracks, "She's gonna make someone reconsider!"
A fearless Tina, 62, impressively went through with the jump, and commented that the experience only inspired her to go higher.
"This is my first jump from the second story. Which gave me the courage to go up higher," she captioned the video.
Beyonce's fiercely fashionable mama later jumped from the third story of the yacht. "Taking my leap of faith! It's a little scary," she admitted.
Of course, this isn't the first time Blue has showed her adorable sass. Last month, the only child of Beyonce and Jay Z shut it down in a hot pink outfit for her aunt, Solange Knowles, and Solange proudly noted that Blue "does her OWN photo edits/selections."
Beyonce and family are currently on a European getaway, as the superstar takes her Formation World Tour to Europe. Check out mother and daughter awesomely twinning in matching Gucci in the video below.
