She also performed songs from the album -- which features iconic songs from the '60s and '70s -- at Hollywood's historic Troubadour club last Friday. "I'm really excited about it," Wilson said about taking the stage. "It's a joy to do. It's so much fun, all this week having shows. This is my fourth show this week (Troubadour) and there's nothing better than performing live."

Wilson said Hanks has been incredibly supportive and enthusiastic about her music career and even flew in recently from a movie location to see her perform. "He's been so great about it and when we were recording, he'd say, 'What did you record today, can I hear it?' And then he'd say, 'Oh, I think that's my favorite track.' Now he just says the whole thing is his favorite, he can't choose."
