The blonde beauty hasn't released a record in six years, as she's been focused on her family and role as CEO of her billion-dollar Jessica Simpson fashion brand.

But now the With You singer is ready to return to her music career and will mark her comeback by collaborating with Grammy nominee Perry.

Perry posted a photo of herself standing alongside a beaming Simpson in the studio, adding the caption: "Fun times with @jessicasimpson."

Last year (15), Simpson revealed her singing plans by telling U.S. breakfast show Today that she had turned the basement of her Californian home with husband Eric Johnson into a recording studio.

Simpson and Perry reportedly first met earlier this year (16), when the 4 Non Blondes singer hosted a party to celebrate the music she wrote for movie Freeheld. Simpson's younger sister Ashlee Simpson was one of the performers, as well as Christina Aguilera, Jessica's rumoured rival during the height of their pop careers in the late 1990s.

Perry was one of the lead producers on Aguilera's massive 2002 album, Stripped, and she wrote and produced the singer's hit track Beautiful.
