Taylor (above), who won tour of the year, said early press reports that the shows would flop "really did wonders for my self-esteem."
"It was great to hear people say that I would be playing to nearly empty stadiums!" she half-joked.
She went on to say that an "unforeseeable factor... was my fans, I owe everything in my life to you."
Oh Taylor, stop it.
Another winner on the night was Cardi B, who replicated her best hip hop win at the Grammys with another trophy for her ever expanding cabinet.
She recorded a video speech (above) as she was "busy doing some things."
Fair enough - those rhymes won't write themselves.
"I gotta thank my haters," she added. "Because y'all be saying mean things and think they discourage me but they make me go harder."
Wasn't us Cardi, we've been with you from the start.
