The younger of the Simpson sisters also recently performed in the musical Chicago. With her Broadway experience behind her, she can now concentrate on her next album.
The star told MTV, "I’m going to go back and figure out what I’m going to do and start writing. I love musical theater, but it’s different than the music I want to do on the album."
Simpson also talked about possible collaborations with other artists, saying, "Robert Smith from the Cure came to my last show in London, and I don’t know if I was more excited about him or that it was the last show! To work with Robert Smith would be an honor."
