Not long after Simpson's announcement, her big sister Jessica tweeted her support. "You have always been so much cooler than me," she wrote, adding a smiley face emoticon.
Last July, Simpson opened up to Nylon magazine about her fourth album, which was partly-recorded at the time. "I'm really proud of the sounds and I'm really excited for it to be an artistic venture," she said. "The sound is a little soulful, a little electronic."
Then this past August, it was revealed that Simpson — who was famously lampooned after she was caught lip-synching during her "Saturday Night Live" performance in October 2004 — was working with Linda Perry, who is responsible for some of the biggest hits from Christina Aguilera, Pink, and Gwen Stefani.
Simpson's last album, 2008's Bittersweet World, debuted at No. 4 on the U.S. Billboard 200 chart, but was still a disappointment compared to the her two previous, Autobiography and I Am Me, which both went all the way to No. 1 during their first week of release.
