Tito Jackson, member of the famous family band The Jackson 5 and brother of Michael Jackson and Janet Jackson, has died at the age of 70, his children confirmed on social media.

“It is with a heavy heart that we announce the passing of our beloved father, Rock & Roll Hall of Famer Tito Jackson is no longer with us,” his three sons — Taj, Taryll and TJ — wrote in an Instagram post.

“We are shocked, saddened and heartbroken,” they wrote. “Our father was an incredible man who cared about everyone and their well-being.”

“Some of you may know him as Tito Jackson of the legendary Jackson 5, others know him as ‘Coach Tito,’ and still others as ‘Poppa T.’ Regardless, he will be greatly missed.”

“It will always be ‘Tito Time’ for us. Remember to do what our father always preached and that is ‘Love one another.’ We love you, Dad.”
