Taylor Swift's Super Bowl highlights: Sealing Travis Kelce and the Chiefs' win with a kiss, dancing to 'Love Story' and leaving the after-party hand in hand

The air was electric at Allegiant Stadium in Las Vegas on Sunday as the Kansas City Chiefs beat the San Francisco 49ers in overtime at Super Bowl LVIII. Adding to the excitement was Taylor Swift’s presence at the biggest football game of the year — and she did not waste time before chugging a drink in the first half of the game!

One week after making Grammy history, the singer flew to Los Angeles from Tokyo, Japan, where she just wrapped a four-day stop on the international leg of her "Eras Tour." She then took a separate flight from L.A. to Las Vegas on Sunday.

Despite the 17-hour time difference, she showed up to support her boyfriend, Travis Kelce, tight end for the Chiefs, in what is now his fourth time playing in the Super Bowl in just five years. Of course, she didn’t come alone.

All eyes were on the chart-topping singer as she arrived with her mother, Andrea; actress Blake Lively; rapper Ice Spice and designer Ashley Avignone.

Swift strutted into the stadium in a black corset-style top, black jeans with rhinestone cutouts and a red bomber jacket — Kansas City Chiefs WEAR designed by Erin Andrews — with the number 60 on the back, representing the year the team was created.

The singer topped off the look with red lips, a custom football clutch by Judith Leiber and a gold necklace displaying the number 87, a nod to Kelce's jersey number.

Meanwhile, Kelce wore an all-black sparkly ensemble, and a matching bag to boot, as he left his hotel for Allegiant Stadium. Talk about a fashion-forward couple!

Who's in Taylor's power suite?

Aside from Andrea, Lively, Avignone and Ice Spice, Swift was seen embracing Travis's brother, Jason, as well as NFL Commissioner Roger Goodell, who chatted with the singer for several minutes as she arrived.

Swift was later joined by singer Lana Del Rey, who approached the suite from the seats below to give her friend a shout-out. She joined Swift in the suite later in the game.

Last Sunday, Del Rey joined Swift in Los Angeles at the Grammy Awards, where Swift won Album of the Year for the fourth time — the first artist in history to win the category that many times.

Taylor and Ashley chug a drink

When the camera caught Swift and Avignone in the first half of the game, the two wasted no time chugging their drinks. As soon as the singer was finished, she slammed her empty cup in victory. No shaking it off here!

Taylor joins Travis on the field to celebrate Kansas City's big win

The Kansas City Chiefs triumphed over the San Francisco 49ers with a nail-biting 25-22 victory — and Swift and her suitemates erupted. Not since the New England Patriots' back-to-back wins in 2004 and 2005 has a team won the Super Bowl two years in a row.

It's also the fourth time the Chiefs have made it to the big game in just five years. Kelce couldn't contain his excitement during the team's victory speech, when he screamed at the crowd "Viva Las Vegas!" with Swift watching him from the field.

After the team's thrilling victory, Swift ran to the field with Kelce's mom, Donna, and his brother, Jason. After he hugged Donna, he said to Swift, “Come here, girl” and they hugged and then shared a long kiss to celebrate.

The celebration continues off the field

After that extra long kiss on the field, Swift joined Kelce and his teammates at the team’s official after-party, held at Zouk Nightclub at Resorts World Las Vegas.

Swift and Kelce were captured on-camera dancing and kissing to her song "Love Story."

They also had a moment when her song “You Belong to Me” came on. Kelce made his way to the DJ booth, and they sang along and pointed to one another from across the room.

They later left together, hand in hand, with Swift wearing Kelce’s jacket — sequins glittering in the night.

They were also at XS Nightclub at Wynn Las Vegas, where they again danced to "Love Story." Though the moment is nearly lost to Jason Kelce, wearing a lucha libre-style mask, hamming it up in the DJ booth.

The couple also ate chicken fingers and fries at 5 a.m., delivered to them in the club's VIP area, according to People.

From Tokyo to Vegas. Next up: Australia!

Once Swift is done celebrating, she'll continue the international leg of her "Eras Tour" in Melbourne, Australia. Until then, she and Kelce can savor the moment!
