Meghan Markle wore a Valentino dress at Katy Perry’s concert over the weekend.

Meghan Markle came to play.

Katy Perry wasn’t the only one having fun with fashion at the finale of her “Play” Las Vegas residency, with the royal turning up in the audience with Prince Harry.

Meghan Markle made a statement at Saturday’s show in a subtly sparkling Valentino minidress that is now sold out but previously retailed for $3,450.

The Duchess of Sussex paired the black ensemble, which was embellished with floral appliqués, with a black coat and matching Christian Louboutin heels and pulled her hair back in a ponytail.

Fans praised the 42-year-old via Twitter for “looking gorgeous as always” in the audience while dancing to “Roar” and other hit Perry songs.

Prince Harry, meanwhile, matched his wife as he sported an all-black outfit at The Theater at Resorts World event.

The former military pilot, 39, and his wife flew into Sin City for the show earlier that same day on Cameron Diaz’s private jet, along with Benji Madden and Zoe Saldana, according to the Daily Mail.

The couple sat in the concert’s VIP section, as did Celine Dion and her 13-year-old twin sons, Eddy and Nelson.

Perry’s fiancé, Orlando Bloom, was also in attendance, toting along his and Perry’s 3-year-old daughter, Daisy, who made her first public appearance wearing a Minnie Mouse costume.

The couple watched Perry perform at The Theatre at Resorts World in Sin City.

Bloom, 46, and the “Hot n Cold” singer, 39, live in Montecito, Calif. — “just down the road” from Markle and Harry, the Duke of Sussex revealed during a 2021 “Armchair Expert” podcast episode.

While Harry noted at the time that the foursome “sort of keep in contact,” Perry once went viral for dissing Markle’s wedding dress and saying sister-in-law “Kate [Middleton] won” with a wink.

Perry gushed about the Princess of Wales, 41, during the May 2018 interview, saying, “It’s amazing what she’s doing with all her humanitarian efforts. You know, the fact that she’s a proud feminist, I love all that. So, I support her as another woman and love her and wish [Markle and Harry] well.”

The Saturday show marked Perry’s “Play” residency finale.

Middleton, Prince William and their kids watched Perry perform in May when the Grammy nominee took the stage for King Charles III’s coronation.

While Harry was present at the coronation ceremony amid his family feud, the prince headed home prior to the performances.

Markle, notably, stayed at home at the time with their two children — son Archie, 4, and daughter Lilibet, 2.
