Cast your mind back to September 2014.
Amid the Scottish Independence Referendum and the release of Lena Dunham's first book Not That Kind of Girl, Taylor Swift was gearing up for the release of 1989 – a Grammy Award-winning album that would catapult her from 'girl next door' country singer to bad ass pop sensation, boasting a 'squad' of friends including Gigi Hadid, Cara Delevingne and Karlie Kloss.
The same month, T-Swift gave an intimate cover interview with Rolling Stones magazine, explaining her upcoming track Bad Blood was inspired by her feud with a fellow female pop star, rumoured to be Katy Perry.

As we all know, one of the lyrics from the Bad Blood is "You know it used to be mad love".
So, it's odd that Katy Perry's new perfume is called 'Mad Love' – a follow up to the Teenage Dream singer's 2015 perfume, Mad Potion.
