The 69-year-old business woman posted a video of Julez’s special day as the 19-year-old sat at the head of the table in front of a cake.

The birthday boy appeared overwhelmed with emotion, smiling as he looked down, as his musically-inclined friends family serenaded him with a melodious rendition of Happy Birthday.

“Love you kid,” Knowles wrote over the reel, accompanied by several red heart emojis.

The grandmother-of-four further expressed her love and pride for Julez in a sweet and hilarious caption.

“Happy Birthday Julez! And happy Graduation!” she wrote under the video. “We are so proud of you [red heart emoji] This is the song Happy Birthday when you get a bunch of singers together,” quipped Knowles, mother to musical legend Beyoncé.

The House of Deréon founder also gave a shout-out to her daughter, Solange, for organizing a “great” party.
