BRITNEY GAGS SAM WITH DOLLAR BILLS!

$50M divorce payoff to zip his lips about odd life as man & wife

DESPERATE Britney Spears has coughed up a whopping $50 million to greedy ex-hubby Sam Asghari in a frantic attempt to keep her mental health problems under wraps and avoid risking a new court-ordered conservatorship, say sources.

The Toxic songbird, 42, scrapped an iron-clad prenup after toyboy Sam agreed not to dish on Britney’s cheating, drug abuse and all-around insanity during their 14-month marriage — revelations that could prove her family was right to control her every move, the sources add.

“Britney wants to buy Sam’s silence and she’s willing to pay dearly for it,” confides an insider. “She wants to bury their past together, along with the secrets he collected!”

Those secrets, according to insiders, are said to include Britney’s:

• Mental unraveling since the conservatorship was lifted;

• Violent outbursts;

• Cheating;
