SHREWISH SHARON ON SHAKY GROUND!

She’s catching heat as Talk’s ratings tank

SHARP - TONGUED Sharon Osbourne’s reign of terror on The Talk is about to be over as fed-up bigwigs plot to take her down a notch, sources say.

The 68-year-old Brit has turned into a diva, according to sources who accuse rocker Ozzy Osbourne’s wife of forcing Marie Osmond to quit her co-host gig last fall and trying to take over the Emmy-winning show after moderator Julie Chen left last year. But now the queen bee is in the crosshairs herself as ratings plunge, sources say.
