One user on Vine posted a hilarious moment between Taylor Swift and Pharrell during a Grammys 2015 performance last Sunday at the Staples Center in Los Angeles.

Known for her cheery and quirky personality, the "Shake If Off" singer started reacting excitedly to a performance while on her seat. She kept glancing back to her seatmate, raising her hands up to express her approval of what she was watching.

On the other hand, Pharrell Williams, who was sitting close to her, didn't look very amused at what she was doing.

Vine user Brendan Jordan captioned the viral clip, "Pharrell judging tay so hard yall," amusing fans of both Grammy Award-winning artists.

The Taylor Swift and Pharrell Grammys 2015 post currently has more than 18 thousand likes and over 10 thousand revines.

Meanwhile, the singer-producer won Best Music Video and Best Pop Solo Performance for his popular hit song, "Happy," of his album "Girl" which won Best Urban Contemporary Album at the prestigious music awards show.

Taylor Swift, however, didn't let her lack of wins stop her from having a good time that night. According to US Weekly, the "Blank Space" singer thoroughly enjoyed the night in an aqua blue Elie Saab gown.

The past Grammy winner even pumped up her arms in excitement when the "Come Get It Bae" singer won Best Pop Solo Performance, reported the publication.

Another of Swift's friends and British newcomer Sam Smith nabbed four trophies while Beyonce was able to take home three awards.

Sunday night also saw some great performances from Pharell, Katy Perry, Annie Lennox, Hozier, Sir Tom Jones, Beyonce, Sam Smith, Mary J Blige, Miranda Lambert, Lady Gaga, Tony Bennet and other legendary musicians.

It was during one of these epic numbers that Taylor Swift got the hilarious judging eye moment from Pharrell at the Grammys 2015.
