Uma Thurman stunned passengers by doing a yoga routine on a recent flight, reports.

The Hollywood star was travelling from New York’s JFK Airport to Utah’s Salt Lake City when she left her seat and began bending and stretching in front of shocked onlookers, the website says.

A source told the New York Post newspaper: “Uma started doing yoga in the aisles. She used the flight-attendant station as a ballet barre, where she stretched and did plies for 20 minutes.”

Most travellers politely looked in another direction and put Thurman’s antics down to a stringent fitness regime.

However, they were surprised to see the health-conscious 38-year-old star race off the plane when it landed and immediately light up a cigarette.
