HoustonKickedOffPlane230.jpgWhitney Houston, 48, was reportedly almost forced to leave a Delta flight on Wednesday after she refused to fasten her seatbelt before takeoff.

The crew members on the Atlanta-to-Detroit flight asked Houston to buckle the belt, but she would not -- why is unclear.

Eventually, she let a flight attendant fasten the belt for her, and the plane took off as planned.

Houston was headed to Detroit to start shooting a new film.

She was apparently aggravated after having missed an earlier flight.
