Stevie's secret

Aerosmith's Steven Tyler has been secretly battling hepatitis C and is now speaking out about it on Extra and also in a new Barbara Walters interview.

"I've been pretty quiet about this," he says. "The band took a break about three years ago. … [My doctor] said now is the time, and it's 11 months of chemotherapy so I went on that, and it about killed me."

He added: "You know, it really hurt. It was a bad, bad period. I'm in AA, and I tried to go three, four, five months with nothing, and it about killed me. Hepatitis C is the one that, of all the people in this room, at least three have it and don't know it,"

Tyler says. "It's the silent killer. I may go on 'Oprah' and talk about this. "
