Britney Spears was booted from the Four Seasons after a major Mr. Moneybags, who occupied the suite just below hers for a cool million dollars a year, called the management and threatened to move out if Mama Spears wasn’t sent packing.

According to gossip columnist Mike Walker:

Britney “had been warned repeatedly by management that a Hollywood bigshot….was complaining about nighttime parties, loud parties, and drunken hoochie-momma’s screaming from Brit’s balcony…”

And get this, when the management asked Brit to pack her bags, she refused to leave!

“I’m sending security up NOW,” Britney was told by management.

“Pack your bags and leave, please. Britney packed up and was escorted down to the street and out the exit by security.”
