Davina McCall has signed a £1 million deal for Big Brother 8.

The 39-year-old's salary has been doubled for this year's series, which will see her continuing to front the live eviction shows, as well as new psychology show Big Brother On The Couch.

A Channel 4 source told the Sunday Mirror: "Davina's worth every penny. She's the face of Big Brother. It just wouldn't be the same without her."
