Tito Jackson has died at the age of 70.
On Sunday, family friend and former manager Steve Manning told Entertainment Tonight that the Jackson 5 star had passed away.
While a cause of death is yet to be determined, Manning stated that he believes Tito suffered a heart attack on a drive from New Mexico to Oklahoma.
Representatives for the Jackson family have not yet issued an official statement, though the entertainer's nephew, Siggy Jackson, confirmed the sad news to People.
Just last week, Tito visited a memorial dedicated to his late brother Michael Jackson in Munich, Germany prior to a gig with his brothers Jackie and Marlon Jackson.
"Before our show in Munich, my brothers Jackie, Marlon, and I, visited the beautiful memorial dedicated to our beloved brother, Michael Jackson," he wrote alongside photos on Facebook. "We're deeply grateful for this special place that honors not only his memory but also our shared legacy. Thank you for keeping his spirit alive."
Born Toriano Adaryll Jackson, Tito was an original member of the Jackson 5.
The Motown-signed group rose to international prominence in the late '60s with hits such as I Want You Back, ABC, and I'll Be There.
Later known as The Jacksons, Tito and his brothers were honoured with a star on the Hollywood Walk of Fame in 1980 and inducted into the Rock and Roll Hall of Fame in 1997.
More recently, the artist had a solo career as a blues musician.
Tito is survived by his 94-year-old mother Katherine Jackson and three sons; Taj, Taryll, and TJ.
