Leonardo Dicaprio had to change seats three times while watching 'Iron Man 2' at the cinema.

The Hollywood actor and his model girlfriend Bar Refaeli were forced to switch chairs numerous times as they tried to catch the recent superhero film - which stars Robert Downey Jr., Gwyneth Paltrow, Mickey Rourke and Scarlett Johansson - at the Los Angeles Century City mall on Saturday (08.05.10).

A source told the New York Post: "He clearly didn't realise you could reserve seats. During the previews, Leo and his group were asked to move three times."

Fortunately the 35-year-old star found the incident amusing, especially when the pair were forced to relocate once again during a preview of his new film, sci-fi thriller 'Inception'.

The source added: "Then, as the trailer for his new movie, 'Inception', began playing, they were asked to move again. They were gracious, and Leo was smiling at the irony of it."

The pair eventually settled down in the front row.
