It seemed like most of the celebrities were having a great time at the Golden Globes. Except for Taylor Swift.

The singer went to the awards ceremony solo, dressed in a dark gown and severe hairdo that made her look much older and, well, a bit on the somber side The style choice was a big change from her normal girly, carefree look.

And her single status didn’t go unnoticed during the show. Host Tina Fey poked fun at Taylor, who is fresh off a breakup with One Direction singer Harry Styles.

“You know what Taylor Swift? You stay away from Michael J. Fox’s son,” Fey said as the audience roared with laughter. Fox's son was there to help stars on and off the stage.

“Or go for it,” co-host Amy Poeher said in Swift’s defense.

“No!” Fey said, continuing with the bit. “She needs some ‘me’ time to learn about herself.”

But perhaps Swift’s most noticed moment of the night came when Adele took home the award for best original song with the theme for "Skyfall," beating Swift.

The cameras cut to Taylor in the audience sporting a McKayla Maroney-like grimace before almost kind of smiling.

Her frown didn’t go unnoticed. The Twitterverse exploded with reactions to Swift’s… reaction.

“Taylor Swift's mean face during Adele's win is my new favorite thing,” one user wrote.

“Taylor Swift is NOT impressed by Adele’s win over her,” another noted.
