Prince William and Prince Harry attended the "Star Wars: The Last Jedi" European premiere without their significant others.

The Duke of Cambridge and Prince Harry attended the premiere of "Star Wars: The Last Jedi" in Europe on Thursday at the Royal Albert Hall in London. The two royals stunned in black tuxedos, but they arrived without their significant others Kate Middleton and Meghan Markle.

Kensington Palace shared a clip of the premiere with Prince William and Prince Harry bonding with the cast of the "Star Wars" on Twitter. "Tonight's Premiere is supporting The Royal Foundation - we are honoured to have so many of those involved in the projects as guests tonight. @EndeavourFund @WeAreCoachCore @fly2pole," the palace wrote in the caption.

According to The Hollywood Reporter, the Duke of Cambridge and Prince Harry made a cameo as Stormtroopers in the film when they visited Pinewood Studios in April 2016. Tom Hardy and singer Gary Barlow were also rumored to have taken the same role.

All four reportedly appeared on the same scene. They will be guarding John Boyega's character, Finn, in an elevator.

Boyega confirmed Prince William and Prince Harry's cameo in "Star Wars" when he joked about sharing a scene with the royals "wrapped in Stormtroopers costume" made for a "strange contrast of a weird family." "It's the best of both worlds for me," the actor added.

According to Us Weekly, Middleton's husband and Markle's fiancé were greeted by "Star Wars" droid BB-8 when they arrived on the red carpet. The two princes were all smiles as they made their way into the premiere.

Later on that night, Prince William was seen chatting with Mark Hamil, who plays Luke Skywalker in the film. On the other hand, Prince Harry was photographed meeting the other guests on the premiere.

Prince William and Prince Harry are huge fans of "Star Wars." It remains unknown why the Duchess of Cambridge and the "Suits" actress were missing in the premiere.

"Star Wars: The Last Jedi" hits theaters on Dec. 15.
