Frenzied NBC execs – panicked after rival ABC’s “Good Morning America” beat the “Today” show for the first time in 16 years – are now so desperate to get MEREDITH VIEIRA back as MATT LAUER’s “Today” show co-anchor they’ve offered to DOUBLE the 10 million$$ salary she earned prior to departing!

Rumors are swirling that “Today” co-host ANN CURRY could be demoted to on-air reporter status because she’s got absolutely no chemistry with Matt – but Vieira obviously does.

Said an insider: “Meredith was stunned by the big-money offer – and incredibly flattered.”

Stay tuned.
