Joan Jett and Miley Cyrus perform 'Bad Reputation' and 'Cherry Bomb' on 'Oprah'

This is a pairing we never expected to see -- and really never expected to love. But we totally love it. Oprah Winfrey invited several classic rockers to her show for her "Rock Goddesss of the 70s and 80s" show airing April 13, and they performed with some younger artists from today's generation.

Joan Jett and Miley Cyrus rocked out together to "Bad Reputation," "Cherry Bomb," and "I Hate Myself (For Loving You)." Jett, who will be 53 in September, sounded as awesome as ever, and her voice blended surprisingly well with Cyrus'.

You've got to love seeing Oprah headbanging in the audience as well.

Miley auditioned for "Hannah Montana" with Jett's classic "I Love Rock 'n' Roll," so it meant a lot to her to be able to perform it. "It's something that's always meant something to me, just seeing Joan stand up for chicks who want to play the guitar," she says.

Jett tells Oprah that rock 'n' roll is her religion. "I take it very seriously and it's important to do what you love. Rock 'n' roll when I grew up really had a context and a meaning, so I felt like it was a religion to me," she says.

She also discussed the role of women in rock. "There are many glass ceilings. I had a really hard time in The Runaways just being taken seriously. A lot of the times you get pushback. I think it's really important for women to try to follow their dreams and push back the pushback."
