Perrie Edwards struggled with her friendship break-up from Jesy Nelson.
The former Little Mix bandmates have not spoken since Jesy, 33, quit the group in 2020 and Perrie, 31, admitted she is devastated about the loss of their friendship.
When asked about how she felt about drifting apart from Jesy, Perrie told Fearne Cotton on her 'Happy Place' podcast: "I wrote a song about it, and it's about a friendship that I had, which I no longer have. I mentioned it in an interview, and so many people reached out to me.
"It's not really spoken about. When you hear a heartbreak song, it's about a relationship or a significant other, and it's like, 'Unbreak my heart'.
"But when it's a friend, you don't hear about it much in music, so I was like, 'I am going to write something about it because it's just as heartbreaking, if not worse'."
She added: "When you have been in that person's life for years, and they have had your back, and you have been through highs, lows, everything and all of these experiences, it's a wild ride, but you are in it together, and then poof, they're gone ... That is hard to deal with. I struggled a lot with that.
"It was really sad, but at the same time, these things happen, and it makes you think, 'Do we try to rectify the situation? Do I reach out? I feel like I should just stay away.' It's a really horrible dynamic to be in.
"You can't force somebody to be friends with you. If they don't want to be friends, they don't want to be friends. But, yes, it's really hard."
Perrie previously shared that she treasures the memories of the fun they had together over 10 years in Little Mix with bandmates Leigh-Anne Pinnock, 32, and Jade Thirlwall, 31, who Perrie is still close to.
She told Cosmopolitan UK: "It was the happiest time of my life. All we did was laugh together, banter together, cry together. It was so much fun. Yes we went through a lot in those 10 years, but we had each other."
