Charlotte Church has agreed a £2 million ($3 million) investment deal with Power Amp Music, the London-based music fund manager, to support the recording of her new album and comeback.

Church, a former child classical crossover artist who later moved into pop and TV presenting, has been writing new material with various co-writers in Nashville and Wales. The album, scheduled for release in the autumn, is being recorded with Grammy Award winning producer Martin Terefe (Jason Mraz, James Morrison, Jamie Cullum, KT Tunstall).

A Power Amp statement said the Welsh artist has sold more than 10.5 million albums.

She is also a judge on the new BBC One TV show "Over the Rainbow," composer Andrew Lloyd Webber's search for musical theater star for the role of Dorothy in "The Wizard of Oz." She appears on Jonathan Ross's (pre-recorded) BBC One show tonight - and the U.K. media has already been getting excited about the 24-year-old singer's weight loss.

Her new deal leaves all marketing and distribution options for the album release open to discussion. Power Amp Music, which launched in 2008, specializes in bespoke funding solutions to high profile, established artists. Their funding deals typically cover several areas of an artist's career, including live and publishing.

Church is the company's second major signing after the British pop band Madness, who released "The Liberty of Norton Folgate" last year.

"This is a very exciting deal with a very simple structure," said Tom Bywater, Power Amp's founder and CEO, in a statement. "Charlotte had a clear vision of what she wanted to do and we have provided the funding for her to achieve those ambitions while allowing her to retain full creative control and copyright ownership."

Church added: "This is a wonderful time to be a recording artist. I am delighted to have signed a groundbreaking deal with Power Amp. It provides me with a financial commitment equivalent to that of a major record company, but with a much greater degree of control and ownership over my career."
