The former Spice Girls singer loves treating herself to a relaxing manicure, but refuses to share nail files, buffers or polish with other people.

A source said: "She brings her own stuff so she doesn't have to worry that
any of the equipment is not sanitary."

The 34-year-old star's unusual habit came to light after she was spotted unpacking a scrubbing brush, cuticle cutters and other nail paraphernalia at Los Angeles' Bonjour Nails salon recently.

Mel is well-known for her polished appearance, and insists she always likes to look her best.

She sticks to a strict diet and exercise regime, but does have "free days" where she can treat herself to any food she likes.

Mel - who does 200 sit-ups, three times a day - said: "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 like it and that's great. I work out, eat healthy and listen to my body."
