Lara Flynn Boyle's air strip

Lara Flynn Boyle allegedly stripped off and attempted to seduce a fellow passenger during a recent first-class flight.

The Hollywood beauty reportedly stripped on the London-bound British Airways flight and tried to climb into the bed of a sleeping stranger, according to Britain's Mail on Sunday newspaper.

Cabin crew attempted to cover the 'Men in Black' star up as stunned passengers looked on.

A witness said: "People recognised she was Lara Flynn Boyle and saw her popping pills on board early in the flight.

"She was half naked , woke a passenger up, tried to get into bed with him, pulled open the blind and said, 'We're landing, get your clothes on,' even though we were more than four hours away from London."

A British Airways spokeswoman confirmed: "First-class passengers on board Flight BA 282 from Los Angeles to Heathrow reported that a female passenger in the cabin was behaving strangely."

However, a spokeswoman for Lara - who was flying to Britain to start shooting new movie 'Land of the Blind' - says the alleged behaviour says it doesn't sound like something her client would get involved in.

She said: "It genuinely is completely inconsistent with her character and behaviour."
