Brittany Mahomes is bejeweled in glittering pajamas at Taylor Swift Eras Tour in Amsterdam

By the way, she’s going out tonight.

Brittany Mahomes joined her husband Patrick Mahomes and Travis Kelce to watch Taylor Swift perform her third and final Amsterdam Eras Tour show on Saturday.

The mom of two, 28, wore a sparkling black pajama set from Prada as she cheered on the pop star.

The silk set, adorned with a polka dot print, cost $7,800 from the luxury fashion brand.

Brittany showed off her dazzling Eras Tour outfit via an Instagram Boomerang of her and her pal, Miranda Hogue, dancing to the show.

She accessorized with a white pendant necklace and her blond tresses curled and styled in a half-up, half-down hairstyle.

The former pro soccer player also shared a glimpse of what her NFL star husband wore, as she posted a photo of him lounging in a private jet ahead of the concert in a matching brown corduroy set.

The Mahomeses finally made an appearance at the Eras Tour after a whirlwind European vacation that included stops in Portugal, Switzerland and London, bringing children Sterling, 3, and Bronze, 2, along for the ride.

The two blonds have become close friends in the past year, bonding while cheering on their husband and boyfriend, who both play for the Kansas City Chiefs.

Page Six Style reported that Mahomes even cemented her friendship further in recent months, tapping devoted Swift stylist Venetia Kidd to dress her for red carpet event such as the Sports Illustrated Swimsuit Issue launch party earlier this year and, most recently, the Chiefs’ Super Bowl ring ceremony.

Perhaps the “Bejeweled” singer, 34, introduced Mahomes and Kidd during football season, when the WAGs often wore coordinating looks and even “twinned” in puffer jackets repping their respective men.

They have also celebrated holidays, charity galas and simple nights out together, both with and without their other halves, though Swift has not been reunited with the crew in recent weeks due to her international tour dates.

Even Patrick Mahomes’ mom gave her stamp of approval, telling Page Six exclusively that their friendship is solid.

“It’s hard at this point to meet people that are true and real and they kind of found each other,” she gushed. “[Brittany and Taylor] really, I mean, talk all the time and they’re like, really good friends.”

And Mahomes has shown her support for Swift outside of the music arena in the past, too, defending her against football fans who threw shade at the songstress.

In February, Brittany reposted a quote from Charles Barkley, in which the former basketballer said, “If you’re screaming at Taylor Swift saying she ruined [football], you’re just a loser.”

Brittany wrote alongside the quote, “Let. Them. Know.”
