So, it seems that all was not well in Camp Talvin long before Swiddleston were a thing.

According to reports, Taylor Swift was FEWMIN with Calvin Harris back in February.

His crime? Not being her plus-one at the Grammy awards, obvs.

According to a report in The Sun newspaper, Calvin decided he'd rather spend the evening making music in his studio instead of celebrating all things Taylor at the glitzy bash.

A source said: "Taylor was furious and hated the way he never wanted to attend award shows and big music industry events with her.

"It was a Sunday night in LA and she felt he could have slipped away for a couple of hours to be with her."

Er. Maybe he just doesn't like big industry 'dos or something?

Anyway, Taylor took her BFF Abigail Anderson instead. So that was nice.

The paper also suggests that Taylor was already making moves on Tom Hiddleston at the time.

The source continued: "Taylor's true colours are coming out. The truth is she met Tom in February and things are moving very quickly. She had vacated her relationship with Calvin way before she let on."
