Houston, we have a...ahh, forget it!

Whitney Houston caused a ruckus aboard a Delta Airlines flight from Atlanta to Detroit Wednesday after she refused to buckle her seat belt before takeoff. 

According to TMZ and People, the 48-year-old singer "got diva" with crew members and ignored repeated requests to buckle up. Airline staffers then threatened to remove her from the flight, only until finally a flight attendant fastened the belt for her.

Houston's reps told People that Houston "wasn't drunk, drinking or on drugs; she was just exhausted." (or, in other words, "stoned off her ass". Whatever works.)

Another insider told TMZ the singer "overreacted a little bit after missing an earlier flight, but she's still 100 percent sober and was on the way to Detroit for her first day of shooting a new movie."
