Katy Perry - Katy Perry: 'I Wasn't Always For Gay Marriage, But I Think It's A Great Thing'

The I Kissed a Girl singer admits she's thrilled by U.S. President Barack Obama's support of same-sex marriage and is excited about the fact so many of her legions of American gay fans can now wed - but she had a very different opinion growing up.

She tells Parade magazine, "I came from a different mindset growing up, and my mind has changed. My viewpoint on all these things - equality for women, the choice to love anyone you want - (has changed).

"Hopefully, we will look back at this moment and think like we do now concerning (other) civil rights issues; we'll just shake our heads in disbelief, saying, 'Thank God we've evolved.' That would be my prayer for the future."
