Whitney Houston Doesn’t Understand Flight Procedure 101: Fasten Your Seat Belt.

Sources report that Whitney Houston was nearly booted off a flight because she refused, simply REFUSED to buckle her seat belt. God knows whether she would agree to put her tray table up.

According to TMZ, the troubled singer – let’s be honest, the girl’s got troubles – was warned that should could be asked to leave her Delta flight from Atlanta if she wasn’t ‘onboard’ with the FCC guidelines.

A crew member actually had to come over and buckle it up for her. Lazzzzzzyyyyyyy! TMZ also reports from a source that Houston “overreacted a little bit after missing an earlier flight (welcome to the real world - flying commercial is a real drag … sorry you have to be a real person!) but she’s still 100% sober and was on the way to Detroit for her first day of shooting a new movie.” I love any person who can do damage control AND give a plug for a new project!
