If you were listening to music in the early 2000s, chances are that the iconic riff from Britney Spears' "Toxic" was stuck in your head at some point.
While experts may already have known, Twitter user @DeleteItFatty just pointed out that the track's earwormy hook actually came from the 1981 Lata Mangeshkar song "Tere Mere Beech Mein".
A lot of people are surprised to know that Spears' chart-topper was inspired by a song from the Bollywood film Ek Duuje Ke Liye.
The tweet got hundreds of retweets in just a few hours.
