"I am so very saddened to hear my longtime friend Ja'Net DuBois has passed away," Jackson wrote, alongside a slideshow of snapshots of the pair taken over the years.

Jackson, then 11, joined the cast in the fifth season as Penny - a young girl adopted by Willona after she's abandoned by her abusive mother.

The pair reunited in 1987 when DuBois played the R&B icon's mother in the music video for her single "Control."

Lear also posted a tribute to the late actress and singer, sharing on Twitter, “Ja'Net DuBois was all light and will be missed. I love that she wrote the theme song for her passing, 'Movin’ on Up'," referencing the theme song to The Jeffersons, which DuBois wrote and sang.
