Jennifer Aniston cursed her hero Sir Paul McCartney's timing when the former beatle visited her on the set of new thriller DERAILED.

The former FRIENDS star was shooting one of the movie's most dangerous scenes when the cast members were invited to meet their surprise celebrity visitor.

She recalls. "We were doing a very intense scene with a lot of the actors and trying to stay focused. It was dangerous and life threatening.

"All of a sudden we get the word that Sir Paul McCartney is here, 'Would you all say hello?' And we're thinking, 'Of all the days you gotta meet Paul McCartney - a Beatle that you worship.'"
