Taylor Swift and Brittany Mahomes looked as thick as thieves in a pair of photos posted on Instagram on Monday.

The photos were shared by the wife of Chiefs quarterback Patrick Mahomes.

Among the pics posted in a carousel on the social media platform were two shots of Taylor Swift and Brittany Mahomes appearing closer than ever. The photos were seemingly taken following Swift’s third and final Amsterdam “Eras Tour” show earlier this month.

Brittany Mahomes captioned the post, “London & Amsterdam, we had a great time.”

In one photo, Brittany Mahomes was wrapping her arms around the global superstar with a smile on her face. Swift pulled her in close and had her right arm around her shoulder.

Another image showed Swift kissing the side of Brittany Mahomes’ head. The Sports Illustrated Swimsuit model smiled and grabbed onto the arm of the “Blank Space” singer.

Brittany Mahomes and Taylor Swift have become close friends since Swift started dating the Chiefs’ tight end nearly a year ago. Their relationship became public in September.

The pair have been spotted watching Chiefs games last season and have been out together numerous times. Their outings have included a dinner at Nobu in Manhattan with Cara Delevingne in late January.

Patrick Mahomes’ mom, Randi, told Page Six in February that the friendship between Swift and Brittany Mahomes was the real deal.

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

Among the other photos in the post, they included the couple’s two children: daughter Sterling, 3, and son Bronze, 1.
