Celebrity snitch Mike Walker claims Rosie O’Donnell is lived after losing “The Price is Right” host gig to recently injured Drew Carey.

Rosie has hissed to a pal that Drew’s “a dated 1990s comedian” – adding that he’s certain to bomb and producers will come running right back to her!

Rosie was demanding that ‘Price’ producers: (1) talk more to contestants, (2) fire Bob Barker’s beauties and hire a chorus line of male Broadway singer-dancers, (3) remodel the show’s set, and (4) throw LOTS of confetti!
