(Meredith/CNN) -- Joe Jackson, father and music manager of the Jackson 5, has died at age 89 a source close to the family tells CNN.
He passed away early Wednesday morning in Las Vegas, family sources told TMZ. There have been multiple reports of Jackson's failing health in recent weeks.
Jackson's son Jermaine told the Daily Mail, "He’s very, very frail, he doesn’t have long. The family needs to be by his bedside — that’s our only intention in his final days."
Jackson's Twitter account tweeted a picture in front of a sunset just this past Sunday.
The tweet read,
"I have seen more sunsets than I have left to see. The sun rises when the time comes and whether you like it or not the sun sets when the time comes."
The tweet came from his official account, though it should be noted his granddaughter Paris Jackson replied, saying it's a beautiful tweet, but she doubts whether he wrote it himself.
this is a beautiful tweet. though it upsets me to see whoever is in charge of this account taking advantage of it. my grandfather did not tweet this. i’m not sure if he’s ever used this account.
Jackson is survived by his wife Katherine and their many children, Janet, Randy, Marlon, La Toya, Jermaine, Tito, and Jackie. Joe Jackson also has another son, Joh'Vonnie Jackson whose mother is Cheryl Terrell. His son Brandon died at birth in 1957 and Michael died in 2009.
Jackson started managing his children and their bands in the early 60s and The Jackson 5 first hit it big in 1966. The band, featuring a 7-year-old Michael Jackson had four singles hit the top spot on Billboard's Hot 100 chart.
The band only lasted a few years, but Jackson had developed an ear for music and believed he had found some talent in his children. He formed The Jackson Brothers in 1963 -- with sons Tito, Jackie and Jermaine -- and began entering them in local talent shows. With the addition of Marlon and Michael, The Jackson 5 was born in 1966. Two years later, they signed with Motown Records.
They went on to become one of the most successful R&B groups in history, with their father initially acting as their manager.
At the height of their stardom, The Jackson 5 sold millions of records and had their own CBS variety show.
"Joseph's role as manager dwindled however as Motown CEO Berry Gordy began to take more charge on his act, a role that reverted back to Joseph when he began managing the entire family for performances in Las Vegas," according to Jackson's official site. "Joseph also helped his sons seal a deal with CBS after leaving Motown."
The success of The Jackson 5 led to Michael Jackson going solo, becoming such a major star that he was later dubbed the King of Pop. Youngest daughter Janet also became a hugely successful recording artist.
The elder Jackson managed daughters Rebbie, La Toya, and Janet in the early 1980s until they, like their brothers before, struck out on their own.
Joe Jackson was criticized at times for being a harsh taskmaster. His children told stories about their father being hard on them growing up.
In 2013 interview with CNN, Jackson was asked about his daughter Janet's complaint that the children were not allowed to call him "Dad," instead referring to him as "Joe."
"You had all those kids running hollering around," Jackson said. "They're hollering, 'Dad, Dad, Dad,' you know, and it gets to be -- it sounds kind of funny to me. But I didn't care too much about what they called me, just as long as they (were) able to listen to me and what I had to tell them, you know, in order to make their lives successful. This was the main thing."
Jackson admitted that he disciplined his children physically but said he had no regrets.

"I'm glad I was tough, because look what I came out with," he said. "I came out with some kids that everybody loved all over the world. And they treated everybody right."
