We are counting down the top five biggest viral videos of the year, but some of the results may shock you — including Carly Rae Jepsen’s “Call Me Maybe.”

The 27-year-old singing sensation debuted her smash single on YouTube Mar. 1 and soon became a prodigy of Justin Bieber after he heard the music-making magic.

But, it isn’t Jepsen’s personal link that topped the viral video charts for “Call Me Maybe.”

Coming in at number 4 on the countdown, with over 55 million YouTube views, is a cover of Jepsen’s “Call Me Maybe” performed by other young Hollywood stars Justin Bieber, Ashley Tisdale and Selena Gomez.

The trio join the roster of A-listers such as Katy Perry, James Franco, and Kelly Clarkson who have all created sing-a-longs to the catchy tune, showing their love for Jepsen’s work.

Of course, number one on the charts should still come as no surprise.

Gaining over one billion views, Korean pop star Psy topped the list with his popular dance video “Gangnam Style” that released on the web in July 2012.

Following the footsteps of Jepson’s YouTube hit, the Korean pop song went Hollywood.  A
