Taylor Swift seemed to have let loose at Brittany Mahomes’ 30th birthday party.

One of Mahomes’ pals, Cass Greinert, shared more photos Thursday from the country-themed weekend celebration — one of which showing the pop star sipping on a martini alongside Mahomes’ group of friends.

Other snaps included Mahomes’ gal pals enjoying a boat day, dancing in cowboy hats and doing karaoke.

“XOXO, take us back to Nashville. ✨” she captioned the carousel of snaps.

The mom of three flew out her besties on a private jet for the weekend of festivities that took place last month. The itinerary included several events including an all-pink birthday brunch, which the singer had to skip.

Swift, 35, was previously pictured cuddling up to the birthday girl during the dinner at a Nashville hotspot wearing a black corset tank top and her Super Bowl “T” necklace.

Fans also spotted the Grammy winner sitting beside her fellow Kansas City Chiefs WAG throughout the night.

In another photo shared on September 4, the “Shake It Off” songstress playfully posed with her martini in hand and dangled a pink gift above Mahomes’ head.

The pals developed a close friendship after Swift began dating Chiefs tight end Travis Kelce who is best friends with Chiefs quarterback Patrick Mahomes, Brittany’s husband.

The “Love Story” singer stunned in a plaid vest and miniskirt set by Simkhai, which she paired with sky-high Gucci platform heels and a Chanel necklace.

In Kane’s carousel, he posted a video of Patrick clapping and blowing out his birthday cake lit with sparklers.

“Happy birthday Pat & congrats TT❤️ thanks for hosting us Britt 🙏🏽.” the musician captioned the birthday post.
