You WON'T believe how much VIEWS Ranbir- Anushka's song garnered

"The breakup song" -- a popular romantic single sung by Arijit Singh, Badshah, Jonita Gandhi and Nakash Aziz for filmmaker Karan Johar's 2016 romantic drama film "Ae Dil Hai Mushkil" -- has crossed the 100-million views mark on YouTube.

The song was published on October 13 last year on the video-sharing site. It features Ranbir Kapoor, Anushka Sharma and Lisa Haydon.

Karan took to Twitter to share the news with his fans.

"And another track of ours crosses the 100 million views mark! 'The breakup song'," he tweeted.

Anushka and Ranbir's sizzling chemistry in the video, and the quirky lyrics, are a few reasons why people are loving the song, which is quite catchy.

"Ae Dil Hai Mushkil" released on October 28 last year.
