Robert PATTINSON and Kristen Stewart put their romantic troubles behind them as they mounted a united front at the world premiere of the final Twilight movie.

The couple, who split earlier this year after she admitted having an affair, were on the red carpet for the screening of the film in Los Angeles.

Stewart, 22, wore a nude lace dress with a strapless bodice as she attended the Nokia Theatre for Twilight: Breaking Dawn Part II, with her hair in a vampish style swept over one shoulder.

British star Pattinson – who plays vampire Edward Cullen – donned a green suit for the finale of the hugely successful series, based on the books by Stephenie Meyer.

The pair, who play a married couple on screen, saw their own low-key romance in the spotlight in the summer after Stewart – who plays Bella Swan – was pictured with married film-maker Rupert Sanders.

There was speculation about how the split would affect the publicity machine for the last Twilight instalment, but they seem to have patched up their relationship – at least for the cameras.
