The pop star ‘gave bit of a side-eye’ when she realised the jeering was directed squarely at her.

Taylor Swift has been booed by fans on her first appearance on the big screen at the Super Bowl in New Orleans.

The megastar is attending the NFL championship game for the second consecutive year to support her boyfriend and Kansas City Chiefs tight end Travis Kelce.

But the crowd inside the Caesers Superdome is clearly favouring the Philadelphia Eagles — as Swift learned early on Sunday night (Monday AEDT).

Swift was shown on the screens inside the stadium after the Chiefs’ first offensive possession and copped serious jeers from fans.

The Associated Press reported “she gave a bit of a side-eye when she realised she was getting booed on the big screens, and kind of wrinkled her nose a bit”.

It appeared she then mouthed the words “what is going on”.

Swift was pictured after actors Rob McElhenney, Adam Sandler and Paul Rudd. McElhenney is a diehard Eagles supporter while Rudd barracks for the Chiefs.

Swift arrived about 90 minutes before kickoff to watch from her suite at the Superdome.

She had arrived in New Orleans days prior to the Super Bowl, with the 14-time Grammy winner and Kelce going to dinner with Patrick and Brittany Mahomes on Friday.

The couples dined at Lilette, a French restaurant near the Garden District.

On Saturday night, Swift was spotted with musicians Danielle and Alana Haim at Gianna Restaurant.

Swift’s commute to the Super Bowl was not quite as long as her first trip.

Last year, she performed in Japan on the Saturday night before the game, taking a flight across nine time zones and the international date line to reach the US and ultimately Allegiant Stadium in Las Vegas for the Super Bowl.

She was joined then by her friends Blake Lively, Ice Spice stylist and designer Ashley Avignone, and her mom Andrea.

She watched the game from a luxury suite, where she was also joined her partner’s big brother Jason, a former Philadelphia Eagles star.

Swift made headlines for chugging a drink when she was shown on the stadium’s video board.

The Chiefs went on to defeat the San Francisco 49ers in overtime, with Swift later joining Kelce and the Chiefs on the field for the post-game celebration.

Last season, Swift was in attendance for 13 Chiefs games, with Kansas City going 10-3 with her in the building.

This season, Swift attended eight of the Chiefs’ nine home games during the regular season, with Kansas City winning each game she was in the building for.

The only home game she missed was a December clash against the Los Angeles Chargers because it fell on the same day as the final concert of her ‘Eras Tour’ in Vancouver.

She also attended the Chiefs’ playoff victories over the Houston Texans in the divisional round and Buffalo Bills in the AFC Championship game, bringing her record on the season to 10-0.

While Swift has made a repeat trip, Kelce’s Chiefs are attempting to three-peat by becoming the first team in NFL history to win three consecutive Super Bowls.
