Over the weekend Basic Instinct star Sharon Stone threw a fit on a flight to Salt Lake City, Utah.  Sources say the trouble began before the actress even boarded the flight, and it had to do with her luggage.

Here’s what a witness to the ordeal told Stylist.com, “The flight attendant in Kalispell asked her to check her bag at the gate and Sharon refused and got into a huge fight with her.  They eventually took the bag from her and she screamed at her assistant with her and made a scene during the entire flight.”

Onlookers say that when the flight landed, Sharon was met by armed Salt Lake City police officers and brought in for questioning about the incident.  No word on whether charges were filed.

As you can imagine, these claims have been denied by Stone’s rep, Paul Bloch, who said that the armed guards were security that Sharon had personally hired to protect her.  He has also denied that she was detained or had an assistant with her.

Bloch stated that Sharon had been visiting her father in Montana and had gotten prior approval to take both bags on board with her.  When she arrived at the airport the stewardess was supposedly the one who caused the scene, yelling at Sharon and not letting her take both bags.
