"I'm still considering," she answered. "But, I will say that I find the more people see, is the more they understand, and then it's the more they like you. If you only have such one-dimensional things to go off of like rumors, then you kind of never get to know the artist. When you pull them in your world, they see you as a real person. I'm not running away from it anymore."

Though The Beach Boys' 50th anniversary reunion tour is winding down in England this week, a version of the group will continue to tour extensively, led by Mike Love. Love will continue to tour with his own version of the group, as he controls the rights to the Beach Boys name. Founding members Brian Wilson, Al Jardine and David Marks will not be involved. Wilson, Jardine and Marks reportedly did not find out until Love released a statement saying "The post-50th anniversary configuration will not include Brian Wilson, Al Jardine and David Marks. The 50th Reunion Tour was designed to be a set tour with a beginning and an end to mark a special 50-year milestone for the band." "I’m disappointed and can’t understand why he doesn’t want to tour with Al, David and me," Wilson told CNN. "We are out there having so much fun. After all, we are the real Beach Boys."
