Spice Girls singer Geri "Ginger Spice" Halliwell is candidly sharing her battle with bulimia for the latest installment of the OWN network’s Where Are They Now? series.

In the episode airing on Saturday at 10 p.m., Halliwell, 44, details living a double life of sorts. As the the Spice Girls shot to stardom in the mid-90s, Halliwell grew obsessed with her appearance, and the glare of the spotlight only made things worse.

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

Unbeknownst to her fellow group members, Halliwell was trapped in a 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," the British pop star explains. "It's bloody dangerous."

With the help of 12-step meetings, Halliwell was able to beat her eating disorder. She's now passionate about baking, having won the U.K.'s Sports Relief Bake Off earlier in the year, and no longer acts out with food.
