Harris and Swift are rumored to be dating for a few months now. The two may not have walked side by side at the red carpet, but they certainly went public by getting cozy during the awards ceremony.

The 2015 Billboard Music Awards is the pair's official appearance together.

After the preview of "Bad Blood," Taylor went to her man for a kiss before going to the stage to accept an award. In addition to the sweet moment, Calvin was also overheard as saying "I love you" to Taylor and telling her how "amazing" she is.

It had been two years since the "Shake It Off" singer had a relationship, and she appears to be happier than ever.

She also looked amazing donning a white and sparkling cut-out jumpsuit for the special event.

Meanwhile, Calvin wore a black button-up shirt and was seated next to her girl. The "Style" singer sat with boy pal Ed Sheeran as well.

The 25-year-old singer is the night's lead nominee, getting 14 nominations, of which include top artist, top Billboard 200 album for "1989," as well as top Hot 100 for her smash hit "Shake It Off," reported Mirror.

"'I am so happy to win this for 1989. We put it out and you guys embraced change [...] for me doing something new," Taylor said while on stage. "I love you more than I will ever be able to say to you. I love you so much."

Before their official appearance at the BBMA 2015, the two have been spotted recently in a series of dates. Earlier this month, Taylor was also seen supporting Harris at KIIS FM's Wango Tango in Carson, California.

It was a major night for Taylor not only because of her official appearance with Harris, but because she also premiered her "Bad Blood" video, which was one of the night's most anticipated events.

In the video, Taylor plays "Catastrophe," fighting the character of her BFF Selena Gomez. The video includes A-list cameos including Cara Delevingne, Lena Dunham, and Gigi Hadid. 

The 25-year-old previously told Rolling Stone that the song was written about rumored rival Katy Perry.
