Hotel heiress Paris Hilton reportedly did not seem to be in a happy mood while on a recent trip from Moscow to London, say reports.

Sources have revealed that she remained “quiet and fuss-free” during the four-hour BMI flight, but became visibly anxious upon touching down at Heathrow.

“She was all set to leave the plane but then business class travellers were told they would have to leave via the rear exit due to some sort of problems. She didn’t look best pleased,” the Daily Express quoted a source as saying.

Things even worsened when two guys she thought were waving to her were actually found to be talking about a little known television star behind her.

“‘Hey, it’s you, you off the TV!” the guys said, according to the source.

“Paris was beaming until it became apparent they were talking about the chap behind her, a little known TV presenter called Martyn Andrews, who hosts the shows Russia Today and Euro News,” the source added.
