TMZ reports that Brooke Mueller on Tuesday got into an argument with the crew of a United jet from L.A. to Cancun.
Just before the plane was about to push back from the gate, Brooke felt nauseous and said she needed to go to the bathroom but the flight attendant told her she could not get up, and things then got heated.
Brooke insisted she had to throw up, but Brooke is telling people the flight attendant rudely replied, "Tough." Brooke then went ballistic and demanded to get off the plane. She says her wish was granted.
Witness on the plane said Brooke was "belligerent and cussing out the flight attendant" so she was removed from the plane.
