Taylor Swift ‘Shake It Off’: Justin Long Unconsciously Sings TS Hit Song While Watching Knicks Game

Actor Justin Long apparently likes Taylor Swift songs, particularly "Shake It Off".

On November 12, Long sat between girlfriend Amanda Seyfried and country singer Taylor Swift at courtside during a game between the New York Knicks and Orlando Magic, where the 36-year-old "Yoga Hosers" actor, at one point, was spotted humming to the tune of "Shake It Off", sung by his seatmate, based on a report by ABC News.

In a video shown by OK Magazine, other big stars were also nearby such as Howard Stern, Kate Upton and her boyfriend Justin Verlander. At the start of the video, Justin Long and Amanda Seyfried was seen sipping their beers.

A few moments later, Stern sat with his partner, showing Long and Seyfriend's astonished looks. Swift and Upton followed about a minute later, shaking hands with the couple before they sat. Swift, Long and Seyfried continued to chat intermittently during the game.

At one point, Long and Seyfried were featured on the Jumbotron with Long showing a surprised look on his face and saying, "Oh my God!" before waving shyly to the camera.

The funniest part was when Long started humming to "Shake It Off", not realizing immediately that Swift sang the song. Long told Huffington Post, "At one point they were playing that song 'Shake It Off' -- that song, you all know it. It's one of those songs that really gets in your head, really crawls in there."

"And of course she heard it. And she was like, 'Oh,' and sort of started laughing, and I was so embarrassed," Long said in the same Huffington Post report.

"I didn't do it so she would hear me. I wouldn't have done it had I been all that conscious of all that," he said. "But she was really sweet about it. She was, like, 'That's the whole point of the album!'"

Long shared that Swift knows a lot about the New York Knicks and was really down to earth. He appreciated the way she responded to his unconscious humming at Madison Square Garden.

US Magazine reported that Long purchased Swift's album 1989 and described it as "incredible". He said, "I don't know why I'm promoting her stuff, she's doing fine!"

Swift is apparently a Knicks fan. In the end, however, the Knicks lost to the Magic 85-87. Carmelo Anthony, nevertheless, gave them a good show by scoring 27 points.
