"I want to have a healthy body image for Bluebell," People quoted Halliwell, as telling the U.K.'s Glamour.
"I think it's good to promote a healthy example, so whatever shape she is, she loves herself. I used to be an exercise freak," said the singer, who has battled bulimia in the past.
"[Now] yoga has always been a consistent, loving thing to do. I'm not into the Madonna-esque yoga-cising. "I think the outside reflects the inside, and where I am now, I just feel content and accepting. I think that's the key to having a good body," she added.
Ginger Spice also added that fame has been good to her, but it doesn't fulfil her, and thus she's writing children's books these days. As for turning her relationship with singer Victoria Beckham around and solving their differences, she said: "I absolutely adore Victoria. She is a very close friend of mine and godmother to my daughter ... she does what she does and I respect and admire her. She's worked incredibly hard."
