From her pop music, like her second studio album Irresistible (2001), to the country sound of her sixth Do You Know (2008), Jessica's been in the game for a minute; she's come a very long way. "I am a woman now and I can do what I want and to have freedom in music — I think that's what you're going to feel in Nashville Canyon."

"I don’t know why my heart gets tossed around but I’m one of the lucky ones," Jessica Simpson tells PEOPLE. "At least I have my children and I still have Eric. He's still very much a part of my life and will always be.

Jessica Simpson has new music coming, and the singer says its helping to heal her heart. Simpson’s “Use My Heart Against Me” will debut this week, the first song off her upcoming “Nashville Canyon: Part 1” project.
