American Idol's sexiest judge stopped by The Ellen DeGeneres Show on Tuesday to chat with the talk show host about his recent engagement, how his bandmates found out he was joining American Idol, and reaching the two-year mark on his sobriety!

The Aerosmith singer tells DeGeneres on meeting now-fiancee, Erin Brady:

    "The first time I saw her, she worked for Clear Channel, so she was
    paying the band. And I didn't notice her, and one night she had on this hair
    band on around her head. She looked really old fashion, so I took her back in
    the room and she tied me up with it
    and I thought I'm marrying this girl. Exactly that way (laughing)."

The 63-year-old also revealed that he never actually told his bandmates he was joining American Idol as a judge, they simply found out for themselves. "A band is like, it's not women. It's men," Tyler said. "It's a different world. We keep a lot to ourselves. Don't often tell the truth. I fell off the stage doing a ZZ Top (song). We didn't speak to each other for the longest time. "

Steven then added that going away to Betty Ford to "fix the shoes that helped me slip," also helped him get two years sober.

    "I can't get back into that world. I can stay high on stage and stay high. I mean out here with you right now my hearts pounding. Hearing you guys (the audience) roar. This what I live for today. But you never know if it's going to stick. I just keep with my program, wish and hope. I don't want to go back to that place. That place lost me, my kids, a marriage, a band. A lot of things and it's for real. That's how dangerous that is. So I take it serious."

Tyler admits he's been to rehab a total of five or six times, so sticking with a sobriety program for two straight years is a huge step for the rock star!
