Steven Tyler 'Ashamed' of His Womanizing Past

Oprah Winfrey will reign in the New Year debuting Oprah's Next Chapter with Aerosmith front man and American Idol Judge Steven Tyler. Beside his longtime girlfriend, the legendary performer opens up about life, love and what it took to finally tame his rock star ways.

Previously an accountant for Tyler on tour, his girlfriend of seven years, Erin Brady, says that although she bore witness to the worst of his bad-boy behavior, she knew his ways could be reformed and she wanted to be the one to do it.

"I saw him, how he behaved… badly," she said, telling Oprah she had to step up to the plate as the womanizing continued when their relationship became romantic. Her strategy was to "play" as he would when Tyler would stray, which he admits was a wake-up call and an instigator towards treating the women of his life with the respect they deserve.

"There was some behavior I am ashamed of and I shouldn't have done," Steven explains. When asked bluntly if he believed he could remain monogamous with Erin, Tyler confidently replied that he could. "I don't want to hurt anybody again. For all the divorces I've had I've hurt those girls deeply."
