Pop star Jessica Simpson has opened up about her decision to relocate from her $18 million Los Angeles mansion in favor of enjoying a much more low-key lifestyle in Nashville, TN —while speaking out about the surprising way the move impacted her music career.

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. The single comes a month after she and her husband Eric Johnson announced are ending their marriage of a decade.

Jessica Simpson says Eric Johnson "will always be" part of her life after she announced their separation last month. The singer, who is releasing her new music this week, reflected on her former relationship with Johnson in an exclusive interview with People in this week's issue, and opened up about how music has healed her.
