LOSER LAUER SHARPENS HIS KNIVES!

Ready to spill in toxic tell-all

- 

FIRED “Today" anchor Matt Lauer is threatening to finally emerge from the hole he crawled into after his stunning fall from grace, boasting he'll settle all old scores with a scathing tell-all book this year, The National ENQUIRER has learned.

"For the past five years, Matt's kept his head down, but now thinks the dust has settled and it's time to get even with everyone who threw him under the bus," an insider dished.

Topping his hit list are former "Today" colleagues Savannah Guthrie, Hoda Kotb and Katie Couric, said the spy.
