Robert Pattinson has admitted that he struggled keeping his laughs under control while shooting with Taylor Lautner for Eclipse.
The pair return to the characters of Edward Cullen and Jacob Black for the third movie in the Twilight Saga to be adapted for the big screen.
Despite playing love rivals in the movie Pattinson reveals that the face to face scenes were difficult to film.
HE told Empire: "Taylor and I are quite literally bitching at each other the entire time.
"We have so many scenes where we're an inch away from each other's faces, just staring each other down. It's hard not to burst out laughing."
Eclipse is released just seven months after New Moon hit cinemas enjoying huge box office success.
New Moon grossed $703 million worldwide and was one of the biggest grossing movies of last year.
Eclipse is released 9th July.
