A native of the Lone Star State, McConaughey got his first big break while attending the University of Texas and had a chance encounter with Richard Linklater, who cast him in "Dazed and Confused," a movie that became a cult classic. But just a few days into filming, his beloved father passed away and Matthew delivered a line in the movie that would become a mantra for him. "Just keep livin'."
That philosophy has served him well. Matthew has found a niche playing guys who are strong enough for men but made for women. His romantic comedy roles have been particularly successful, and next week he releases another film: "Failure to Launch" with Sarah Jessica Parker. McConaughey plays a mid-30s bachelor whose romantic life is complicated by the fact that he lives at home with his parents.
His own parents had a loving but unstable relationship. The couple divorced and remarried several times, and were married on and off for 39 years.
Their marriage certainly affected McConaughey's own perspective on relationships. "They would say this in jest, but there's some truth to this as well. Both of them at different times said, 'Well son, I love your mother. Six days a week.' And Mom said the same thing, 'I love your father six days a week. That didn't mean they didn't love each other on the seventh day; what it means is they said you gotta have time for yourself, you can't lose yourself," he tells Walters.
McConaughey has been linked with his co-stars in the past, and has been in a relationship for the past two years with actress Penelope Cruz, who starred with him in "Sahara."
He's happy, he says, but he's coy when Walters asks about his own plans for marriage. "I'll say this. You've gotta find the right woman, and it's gotta be the right time. Have I met the right woman? Possibly."
From humble Long Island, N.Y., roots, Mariah Carey has earned her place on the R&B throne alongside other legendary ladies like Aretha Franklin, Whitney Houston, Chaka Kahn and Gladys Knight.
In her wide-ranging interview with Walters, Carey talks about her childhood growing up in a tumultuous interracial family, her broken marriage to Tommy Mottola, her recent emotional breakdown and the album that garnered her three Grammys.
Through all the tough times, Carey says music saved her life.
"From the time I started singing, which was basically by the time I started talking, I knew that music was just something I had to have near me," Carey says.
She says she used to take the radio from the kitchen and put it underneath the covers when she was 4 years old, and just sing along with whatever was on the radio.
"It was always that release for me," she says.
Another release from the mayhem of the record business is enjoying her 12,000-square-foot Manhattan apartment designed by the famous Mario Buata. She took Walters through a tour of the impressive bachelorette pad.
The pop singer escapes there to watch movies in the mermaid room, to play with her famous dog, Jack, in the kitchen and to rest her voice by sleeping in a customized steam room. She even entertains in her living room where her idol Marilyn Monroe's piano is placed, almost as a shrine.
On a floor below, one bathroom is dedicated to Marilyn and another is a playful repository of all things Hello Kitty, gifts mostly from her Japanese fans. It is also there where Carey, 35, becomes Mariah, the superstar.
