Los Angeles, California - After Taylor Swift turned heads with her fashion choice for Sunday's Grammy Awards, Swifties once again challenged her boyfriend for the star's attention on social media.

The 33-year-old singer was up for four awards at the ceremony, and ultimately took home the prize for Best Music Video.

But as Swifties fawned over her latest look, fans got a rather bizarre topic trending on Twitter as stars walked the Grammys red carpet.

"Can Joe Alwyn fight???" Swift's stans everywhere seemed to ask in unison as they looked to take on the British actor for a chance with the Anti-Hero singer.

Oddly enough, this is not the first time the 31-year-old's name started trending on social media thanks to his famous girlfriend.

Also, unexpectedly thrown into the mix was Swift's former bestie Karlie Kloss, whose name also began trending on Twitter during red carpet arrivals at the Grammys.

There's a surprisingly significant sect of fans that hold fast to the theory that Swift was romantically involved with the 30-year-old model back around 2014.

These Swifties echoed the challenges made to the Conversations with Friends star as they shared photos of Swift's Grammys look with the caption, "Can Karlie Kloss fight?"

Though Alwyn rarely attends public events with the Lavender Haze artist, he's kept fans updated on their romance with subtle nods to Swift, like sharing photos of her cat, Meredith.
