Blue Ivy Carter beat her grandmother Tina Knowles-Lawson in a dance-off to Beyonce and Jay-Z's new song 'APES** T' during a family holiday in the sun.
The six-year-old daughter of Beyonce and Jay Z took on Tina in a friendly contest, and the House of Dereon designer admitted the youngster "killed it".
Sharing a video on Instagram of her own take on Bey and Jay's duet 'APES** T', she wrote: "This is my dance off with Blue!! She beat me of course! We had to make up an original dance move.
"My awkward shoulder move was my made up dance. I know it's wrong but my competition is only 6. She killed it though!!! #aboutthatcaftanlife. [sic]"
The clip was taken as the family enjoy a summer break in the south of France - and it's not the first time Tina has shared an adorable story of her granddaughter.
Back in May, Blue Ivy scolded her for breaking the rules in a theatre in Paris and filming inside when she wasn't allowed.
As the pair sat in their seats waiting for the production to begin, Tina to took to her Instagram account to share the experience with her followers.
Posting a video, Tina, 64, said: "I'm in Paris, France and I'm at the most beautiful theatre I've ever seen in my life about to look at the ballet. It's a walking ballet, it's so cool."
However, rule follower Blue interrupted her grandmother to remind her that filming inside the venue was prohibited.
The youngster said: "You're not supposed to take videos grandma. You're not supposed to."
But Tina - who was previously married to Matthew Knowles, who managed Beyoncé's girl group Destiny's Child to the top of the charts - ignored Blue's warning and finished off her short video by saying: "Such a gorgeous theatre. The architecture is beautiful. Really pretty."
