The British girl group caught up with E! News while promoting their latest album, Glory Days, and when asked about what (or who) inspired the song, Perrie kept things rather... vague.
"When people go through break ups, you automatically want to hear really sad songs," Edwards, who famously dated Zayn Malik, shared. "You want to listen to [Toni Braxton's] "Un-Break My Heart" and have a little cry, get a tub of ice cream out."
The 23-year-old continued, "We just thought, ‘You know what? Women need to feel empowered.' Everybody needs to feel empowered after a break up and we feel like this song can relate to everyone because everybody's had an ex."
Perrie and the "Like I Would" singer were engaged for two years before ultimately calling it quits in August 2015. Two months later, Malik and Gigi Hadid coupled up, prompting many Little Mix fans to wonder whether or not Perrie was fighting back against the swift rebound with "Shout Out to My Ex."
At the end of the day, Edwards is grateful for having such close bandmates to lean on when it comes to facing struggles, fame-related or personal. "We have each other luckily, so we experience everything together and we've always got each other's backs," she added.
As for how Perrie, Jade Thirlwall, Leigh-Anne Pinnock, and Jesy Nelson cope with their superstardom, she told us, "I think you have to learn to have a thick skin. I think it comes with being in a girl band and being an artist. People want to know what you're doing and what you're up to, which is fine with us."
