"Babygirl the IMPACT that you have left in the years you spent here with the world is UNDENIABLE. Leaving generations to know your name 'AALIYAH'," wrote the Grammy-winning rapper, 53, who wrote and produced songs from both the "Rock the Boat" singer's One in a Million and self-titled albums.

The Rock & Roll Hall of Fame member then turned her attention to Aaliyah's brother, Rashad Haughton, who recently teamed up with Mattel on a Barbie doll modeled after his sister to celebrate her birthday and overall legacy.

"Much love to you," wrote Elliott, tagging Rashad. "your sis would be proud."

The star was especially known for her iconic '90s style, and the new Barbie's outfit was drawn from her "One in a Million" music video.

"'One in a Million,' it makes little girls feel special," Rashad explained in a recent interview with PEOPLE. "It's having a dream. It's a beautiful song about love and having a special love. So all these different elements, just from a metaphorical standpoint, were perfect."

Aaliyah's brother predicted his sister would be "elated" to see the Barbie. "She did things so they were right and they felt good," he said. "So she would be so happy of how the execution went down and that it looks so much like her."
