Prince Harry and Meghan meet Beyoncé and Jay-Z at 'Lion King' premiere in London

Duchess Meghan marked her first red carpet appearance as a royal.

British royalty met music royalty Sunday when Prince Harry and Meghan, the Duke and Duchess of Sussex, met Beyoncé and her husband, Jay-Z, at the European premiere of "The Lion King" in London's Leicester Square.

The two couples reportedly talked about parenthood ahead of the premiere of the live-action remake of the children's classic, in which Beyoncé voices the character of Nala.

The original version of "The Lion King" is of special significance to the Duke and Duchess of Sussex. Harry has named it as one of his favorite movies and has said he and Meghan watched it on a date night.

The version Harry and Meghan watched at Sunday's premiere is a live-action revamp of the 1994 original Disney film, starring everyone from Beyonce to Donald Glover, Billy Eichner, Seth Rogen and Chance the Rapper.

Harry and Meghan left their newborn son, Archie, at home for their parents' night out.

Meghan's appearance at Sunday's premiere was also a first for the duchess, who wed Prince Harry last year. It marked her first red carpet appearance as a member of Britain's royal family.

Harry has long been a supporter of conservation efforts, particularly in Africa, where he took Meghan to visit in the early weeks of their courtship.

The Duke and Duchess of Sussex are also planning to make an official visit to Africa this fall. It is expected the couple will bring Archie with them too.

Meghan has been on maternity leave since giving birth to Archie in May but has made several public appearances in recent days. She attended Wimbledon twice, including joining Duchess Kate at Saturday's final.

She also stepped out with Kate earlier in the week, with Archie in tow, to watch Harry and Prince William compete in a charity polo match.

"The Lion King" opens nationwide Friday, July 19 from Disney, parent company of ABC News.
