Brad Pitt recently ended his storied four-year marriage and tabloids are filled with rumors that he has begun a relationship with a Hollywood bad girl, but the "sexiest man alive" denies speculation that he is having a mid-life crisis.
"No, not yet," the 41-year-old actor told "Primetime Live" co-anchor Diane Sawyer. "I keep waiting for it to rear its ugly head -- maybe I do -- I don't know."
In January, he announced that he and his wife of four years, "Friends" actress Jennifer Aniston, were separating. They later filed for divorce. This spring, he was photographed walking along a beach in Kenya with actress Angelina Jolie and her son.
But Pitt does not deny it has been a time of change for him. He has bleached his hair for fun. He is also preparing to move from the Beverly Hills mansion he shared with Aniston.
"Someone will enjoy it," he said. He said he doesn't think he would ever live in a house that big.
Pitt says he now wants "a simpler life." He continued: "I have so much crap -- it just accumulates. I have this romantic idea of getting my closet down to … a little pile of clothes."
Pitt once said that fame is a young man's game. He now acknowledges he's getting older. When Sawyer asked him, "Creaky?" he responded laughing, "Cranky?"
Asked about his marriage, Pitt said, "I don't see my marriage as any kind of failure. It was an extraordinary time."
He said that before they went their separate ways, he and his wife talked about everything -- they didn't hide who they were or what they wanted in any way. "That's always been the basis of Jen and I," he said.
That's also how he and Aniston decided together to move on in their lives, he said.
"As far as I know, we get one shot at this thing. One time around, and it better be everything you want it to be," he said. "I actually think it was a really brave -- conscious -- conscientious decision on our part."
In a 1997 interview, Sawyer asked Pitt if he believed in happy endings. At the time, he responded: "Yeah, absolutely."
Today, Pitt says "I don't even believe in happiness as a concept … I believe more in peaceful endings."
One new focus in Pitt's life is a nationwide movement called The ONE Campaign, aimed at convincing Americans to fight poverty and the spread of AIDS in Africa. The movement has attracted both Hollywood liberals and Christian conservatives.
"In 10 years we could halve extreme poverty … in 20 years we could end it," Pitt said.
Pitt has even traveled to Africa several times, and brought Sawyer along with him on one visit.
Many of the sites Pitt visited in Ethiopia were sponsored by Save the Children.
Bono, the lead singer of the rock group U2, who has been involved in relief efforts and helped found the ONE Campaign, said of Pitt: "He is an extraordinary man. He's this, you know, you know, gigantic movie star, but he's very modest. And he just said, 'Is there anything I can do for you?' "
Pitt recounted to Sawyer an experience he had while visiting a hospital in Ethiopia.
"I remember one boy specifically laying in his crib, and I just put my hand on his chest," he said.
"This wave of bliss came over his face -- and the power in that -- the power in just the human touch. Broke my heart."
Organizers say aiding Africa can help raise America's profile in the world.
