Facing fallout from a recent arrest, TI raised money for his family's new Alzheimer's disease charity and explained how the idea for it took shape during a previous period of legal trouble.
The rapper, whose real name is Clifford Harris Jr, and his wife, Tameka "Tiny" Cottle, held a luncheon for the foundation called For The Love Of Our Fathers, which honours their fathers' battles with Alzheimer's disease.
The Grammy winner would not talk about his arrest last month on suspicion of drug offences, but said the inspiration for the foundation came in the aftermath of his 2007 arrest on weapons charges.
"It's very, very personally close to our family," said TI, who served seven months in prison for the firearms offences. "And while I was, you know, while I was going through my ... period of hiatus, Tameka had the idea of ... starting this foundation. And I thought it was an outstanding idea."
Cottle's father, Charles Pope, has Alzheimer's, an irreversible neurological disorder that causes its victims to lose their memory, become disoriented and suffer personality changes. No cure is known. TI said his father and grandmother also had the disease when they died.
The couple said the charity will raise funds for disease research and possibly offer relief to caregivers.
Nicknamed the King of the South, TI has sold millions of albums and created the hits Whatever You Like and U Don't Know Me. He recently stared in Takers, a movie about an armoured car robbery gone wrong, and is working on a new album.
