Royal siblings walk red carpet

Prince William and Prince Harry joined the cast of "Star Wars: The Last Jedi" at the film's European premiere Tuesday, delighting fans who braved the London cold for a glimpse of Hollywood stars and British royalty.

Cast and crew were silent on reports that the royal siblings make a cameo appearance in the film.

The tuxedo-clad princes walked the red carpet at London's Royal Albert Hall for the black-tie gala, a benefit for their Royal Foundation charity.

Royal officials have refused to comment on reports that the princes recorded a scene playing Stormtroopers when they visited the film's set in April 2016. At the time they were filmed meeting crew members, battling with light sabers and hugging a Wookie.
