The Kansas City Chiefs have emerged victorious after a nail-biter of a Super Bowl, winning their third championship in five years – watched by a jubilant Taylor Swift.

The Chiefs took on the San Fransisco 49ers in Las Vegas as they vied for back-to-back Super Bowl championships on Sunday (US time).

For just the second time in Super Bowl history, the game went into overtime after the score was tied at the end of full-time.

The 49ers got a leg up in overtime with a field goal. But, with just seconds left on the clock, the Chiefs won with a touchdown, to make the final score 25-22.

While the attention of millions centred on pop icon Taylor Swift and her Kansas City boyfriend Travis Kelce, many Australian eyes had another focus. Former Perth tradie-turned-49ers punter, Mitch Wishnowsky was on the field, hoping to make history as the first Australian to play in and win the Super Bowl.

In the opening quarter, Wishnowsky kicked the ball an impressive 54 yards (49 metres) in his debut for the 49ers. The former AFL player earned plenty of praise from commentators, but couldn’t quite turn that into the winning formula.

There was also a bizarre moment in the game’s opening half when Kelce was seen yelling furiously at one of this coaches, Andy Reid, as he was sidelined after a fumble.

The scoreline remained at 0-0 until into the second quarter. The 49ers’ Jack Moody kicked a field goal from the 55-yard (50-metre) line, making it the longest of its kind in Super Bowl history.

But the record didn’t last long. In the third quarter, the Chiefs’ Harrison Butker kicked a field goal from the 57-yard (52-metre) line to get his team in front.

Usher shines at half-time

But the Super Bowl isn’t just about the game. For many across the world, it’s all about the half-time show.

With the half-time score at 10-3 in favour of the 49ers, Usher emerged at Las Vegas’ Allegiant Stadium for Sunday’s show seated on a throne.

He was accompanied by a marching band and a trove of performers. He opened with his 2005 single, Caught Up.

Usher took the stage for the Super Bowl Halftime show.

Usher was joined by Alicia Keys, who started off with If I Ain’t Got You before he joined her for a duet of My Boo.

Across the performance’s 13 minutes, Usher brought out guests including H.E.R., Jermaine Dupri, and Lil Jon – for Turn Down for What, which became Yeah! and featured a guest appearance from Ludacris.

Taylor Swift downs a drink

Swift brought her own star power to the night, sitting in the front row of a private suite to cheer on Kelce.

In recent weeks, the couple’s romance has attracted a new audience to NFL. A surge in women have turned to watching Chiefs games, in hopes of catching a glimpse of Swift.

The effect even spilled over into the Super Bowl’s famous ads, with plenty on Sunday aimed at women. One even played on the singer’s attendance uniting fathers and daughters.

After her dash back from performing in Tokyo at the weekend, Swift made quite an entrance to Allegiant Stadium on Sunday. She was flanked by Ice Spice, Blake Lively, her mother Andrea and Brittany Mahomes, the wife of Chiefs’ quarterback Patrick.

Swift could be seen singing, dancing and engaged in the match. At one point, with the camera aimed at her suite, she downed a drink and slammed the cup down, as if to say she is just like many other sport fans.

As the game went on, Swift watched on nervously but was seen celebrating wildly with her friends after the final touchdown. She and Kelce also shared a very public kiss during celebrations on the ground after the match.

Swift was far from the only celebrity in the stands at Allegiant Stadium. In fact, she was seen speaking with her friend, Lana Del Rey, who later joined her in the suite, and also Sir Paul McCartney.

Jay-Z was also there with his daughters, Blue Ivy and Rumi. All three were on the field before kick off.

Wife Beyonce was also at the game. One of the ads during the match teased her new album (coming next month), while a new song, Texas Hold ‘Em, dropped mid-game.

Long-time Kansas City Chiefs fan Paul Rudd also made it a family affair with his 17-year-old son Jack. Elsewhere, Justin and Hailey Bieber were also in the crowd.
