Mel B is "obsessed with underwear".
The former Spice Girls star - who became the face and body of lingerie brand Ultimo in April this year - loves underwear so much she only has beautiful sets and never keeps any bras or panties past their best.
She said: "I never have embarrassing knickers. I've always been obsessed with underwear and toiletries. I've always kept that together, so I have perfect underwear."
The 33-year-old singer - who has two daughters, Phoenix Chi, nine and 17-month-old Angel Iris - recently revealed she is so comfortable with her body she would consider appearing nude in Playboy magazine.
Mel has turned down two offers to appear in the adult publication, but hasn't ruled out the idea completely. She said: "I was offered Playboy last year and again a couple of months ago, and I did turn them down, but that's not to say I wouldn't consider it in the future. I have no problems walking around the house naked or anything.
"I'm pretty confident with my bikini body. It's not like I've got a skinny body either - it's very voluptuous. But I do like it and that's great. I work out and eat healthy and listen to my body."
