Horner has since reconnected with her former bandmates – and is even planning a reunion with the erstwhile Baby and Scary Spice. But, while she has apologised for leaving the group in the first place, she has revealed that she had a very good reason for doing so: it was an act of self-care.

In a preview of a forthcoming interview with Oprah: Where Are They Now?, Horner explained that she grew obsessed with her appearance – and the glare of the spotlight made things even worse.

“I felt much more conscious of myself, my body weight,” she said. “We all used different tools to get by, coping mechanisms. For me [it] was controlling my body weight.”

She soon found herself trapped in a dangerous cycle of dieting, “comfort eating”, and “purging”.

“I started being bulimic and no one would notice it because your body weight stays pretty much the same,” she said. “It’s bloody dangerous.”

Thankfully, with the help of 12-step meetings, Horner was able to beat her eating disorder. She says she is now in a happier place than ever, and makes a conscious effort to promote self-kindness on her social media feeds.
