The hit single featuring Bruno Mars was viewed over 1 billion times on the music video site during 2015.
Earlier this year the track became the fifth biggest-selling single in UK chart history. The song, released in November 2014, has sold more than two million copies, surpassing the overall sales of Paul McCartney & Wings' 1977 single 'Mull of Kintyre'.
Meanwhile, Taylor Swift dominated the Top 10 with three of her songs - 'Blank Space' which came in at Number Two, 'Shake It Off' at four with over 700 million hits and 'Bad Blood' at seven with over 600 million clicks.
Just behind her at eight was Adele's comeback single 'Hello' which has already racked up over 500 million hits since the UK chart topper was released last month.
She was followed closely by Sia's hit 'Chandelier' in ninth place. She recently performed new single 'Alive' on The X Factor.
Sia sang the song from behind her trademark face-obscuring fringe, complete with a huge black bow and oversized white shirt. Although normally joined by dancer Maddie Ziegler for her live performances, Julia Spiesser from France was on stage for the TV appearnace.
