Golden Globes 2019: Taylor Swift makes surprise appearance, presents award to Lady Gaga

Surprise!

Taylor Swift made an unexpected appearance at the 2019 Golden Globe Awards on Sunday night, where she presented the awards for Best Original Song and Best Original Score alongside "Cats" co-star, Idris Elba. 

Fans had been on high-alert during the pre-show red carpet coverage to see if she would attend the show alongside her boyfriend, British actor Joe Alwyn, who appears in nominated films "Boy Erased," "Mary Queen of Scots" "The Favourite," but she was nowhere to be found on the star-studded carpet. Instead, Alwyn walked the red carpet solo.

The conclusion was that Swift had not attended the show, so when she was introduced as a presenter alongside Elba, it came as a huge surprise.

Swift hit the stage in a sexy, strapless black Versace dress with a lace-up corset bodice and a thigh-high slit. She wore the sheer number over a nude underlay and paired it with one of her signature messy updos, strappy black heels Lorraine Schwartz jewels.

Pop music fans were given a fun moment, too, when, after presenting the award for Best Original Score to Justin Hurwitz for "First Man," Swift presented Best Original Song to Lady Gaga and Mark Ronson for "Shallow," which they wrote for "A Star Is Born." The pair kissed on the cheek as Gaga took the stage, and they also walked off with their arms around one another after Ronson and Gaga's speech.

Us Weekly cited an eye-witness that revealed how Alwyn reacted to seeing his pop star girlfriend onstage.

"While Taylor presented, Joe watched the teleprompter near him and smiled and [his 'The Favourite' costar] Nicholas Hoult patted him on the back," the source said. "After Gaga walked on stage, Joe shifted his gaze to the stage near Taylor. She was smiling at him while she walked off the stage. She looked over her shoulder and gave a sassy cute little smile in his table's direction."
