Photos show Tom Cruise helping Kate Middleton walk up the stairs of a red-carpet event

Prince William and Kate Middleton attended a "Top Gun: Maverick" screening this week, and interacted with the film's leading star while there.

The Duke and Duchess of Cambridge attended the event in London, England, on Thursday, and were joined on the red carpet by Tom Cruise.

The trio headed up a small set of stairs at one point during the event, which could have been difficult for Middleton as she was wearing a form-fitting Roland Mouret dress and pointed-pump heels.

That's when Cruise stepped in and held the royal's hand for support, as seen in photos taken on the red carpet.

The British royals and Cruise appeared to have a conversation during their walk, but it was Middleton who stole the show at the event.

She stood out on the red carpet thanks to her gown — which was black with a white, off-the-shoulder neckline — as well as her accessories.

The duchess wore star-shaped earrings, a black clutch, and her family-heirloom wedding ring. Middleton also donned neutral makeup and her hair in a sleek yet wavy style.

After making it to the top of the event steps, the duke and duchess greeted other stars from the movie. Still, they stayed near Cruise and continued chatting with him.

Cruise and Prince William matched in traditional tuxedos and black bow ties. The prince's shoes, however, were a little more fun.

He wore loafers designed by Crockett & Jones that were embroidered with F-18 planes in honor of the movie.

Middleton and Cruise seemingly enjoyed their time together, with some photos taken at the event showing them sharing a laugh as Prince William talks to other attendees.
