People have caught 25-year-old singer Taylor Swift and 31-year-old DJ Calvin Harris out and about on a few different occasions, but the two hadn't confirmed any of the dating rumors until now.

At Sunday night's Billboard Music Awards, Swift was the talk of the show, winning eight awards and debuting her newest music video, but what people really went crazy over is who she was hugging after each win.

Swift and Harris sat next to each other the entire show and seemed to be crazy in love. They would hug after each win and even shared a few kisses.

An insider told Hollywood Life that Harris was the one who was skeptical about PDA at first, claiming he wasn't really used to it. And considering Swift's fame, he had to get used to it fast.

"They were touchy feely during the start of the night but once the cameras were all in their faces they didn't want to take away from the show so they settled it down a bit," the insider said. "But they really are very happy with each other."

Harris is getting used to the PDA quickly because "he really likes her and she definitely wears the pants in the relationship." The two love that they are finally open about their relationship to the public.

The two were also kissing at Taylor's after party in Vegas, Entertainment Tonight Reports. They were among many big stars in a few photo booth pictures, and you can see them locking lips in the background of one of the shots.

The musical duo seems really happy together and rumor has it that Calvin is going to tag along on her 1989 World Tour.
