However, her album won't be out until October. She broke the news on Twitter.

A lot has happened since Hilary's last 2007 album, Dignity. She got married to former hockey player Mike Comrie in 2010, split from him this past July and has a two-year-old baby with him named Luca.

In fact, she told Radio Disney that her two-year-old son has been listening to "a lot of Hilary Duff these days." She said, "It's sweet because…before he hears my voice and he just hears the beginning of a song, he's like, 'Oh, momma's song!' He definitely knows what's up and he knows it's me."
