The 'Blank Space' singer and her Scottish DJ boyfriend sat next to each other at the MGM Grand in Las Vegas and made no secret of the fact they are together: Calvin even gave Taylor a big hug and a kiss when she won an award!
Cameras caught the cute couple checking their phones together, giggling together and chatting with the people sitting around them, which included Taylor's close friend Ed Sheeran.
No doubt Calvin was a VERY proud boyfriend by the end of the night as Taylor walked away with a mammoth eight awards. YES! Eight awards!
She scooped prizes including 'Top Artist', 'Top Female Artist', 'Top Billboard 200 Album' and 'Top Billboard 200 Artist'. She also debuted her star-studded music video for new song 'Bad Blood'.
Taylor and Calvin first fuelled rumours they were dating back in April, when they were pictured holding hands after leaving a club in Hollywood. They were also seen together at a concert looking very close and cuddly.
Although Taylor is known for having a slew of famous ex-boyfriends, she recently said she doesn't want her love life to be in the spotlight. She told Glamour magazine she felt she'd been "publicly humiliated" over past failed romances and it had made her wary of dating in the limelight again.
"There is no easy way for me to engage with romance. I'm really busy, so I can't. And it's a good thing that I feel really independent and I feel that my friends are all I need. It's kind of a sad way I got there though, being shamed into it. What else is it when you have two boyfriends in one year and everyone's calling you boy crazy, making jokes about you at awards shows? That's public humiliation. And I don't think it's fair."
