The pop superstar -- who turned 35 on Friday, Dec. 13 -- celebrated her latest achievements alongside boyfriend Travis Kelce at an Eras Tour-themed party days after wrapping her record-breaking tour in Vancouver on Dec. 8.
Other pictures showed Swift in a black dress and her signature red lipstick with her hair pulled back. The singer posed with Brittany along with Chiefs WAG Lyndsay Bell who rocked a Lover-esque bright dazzling pink ensemble and Swift's friend Ashley Avignone, who donned a snake around her neck a la reputation.
Partygoers dressed up for the theme with feather boas and colorful clothes to go with her different albums.
Friendship bracelets and light-up bracelets were scattered on the table of the cozy venue, also a cute nod to the Eras Tour.
On Swift's birthday, the NFL honored Swift by sharing a romantic video featuring her and Kelce. The video contained heartfelt clips of the couple set to John Legend's romantic song "All of Me," covered by Toby Gad and Celina Sharma.
Notable moments include the time Kelce, 35, took part in her London stop of the Eras Tour and when she ran to him for a kiss after he came to see her perform in Buenos Aires.
The video also includes clips of Swift and Kelce hand-in-hand after various Chiefs games over the last two seasons, not to mention some of the "Karma" singer's best game-day looks -- including her custom-made "87" jacket by Kristin Juszczyk.
Late last week, Ed Kelce opened up about getting a special gift for Swift on her big day, noting that it's not always so easy during a conversation on the Dec. 12 episode of the Baskin and Phelps podcast.
"Buying Taylor a present is like trying to buy Jason or Travis a present," he explained. "There's nothing they want that they don't already have."
Ed's solution? He aims to "get something that tweaks the strings of her heart that you spend 10 bucks on. Then she'll just be all gooey. You got to find something that triggers the emotion."
This year was full of major career highlights for Swift. Her 149-show Eras Tour reportedly earned a whopping $2,077,618,725 in ticket sales, according to the New York Times. The 14-time Grammy winner also concluded her global, record-breaking tour with a final show on Dec. 8 at BC Place in Vancouver.
During the performance, there was a moment where fans sang "Happy Birthday" to the star in honor of her then-upcoming big day.
And with over 26.6 billion Spotify streams in 2024, the streaming platform named her the most-streamed global top artist for the second year in a row, an achievement Swift called "unbelievable."
"Top Streamed Artist AND Album on @spotify this year?! You guys are unbelievable," she said in her Instagram Stories. "What an amazing thing to find out going into our last weekend of eras shows 💋 THANK YOU!"
