Kelly Clarkson getting healthy for motherhood

Singer Kelly Clarkson has embarked on a major health makeover, so she can become a fit mom as soon as she weds fiance Brandon Blackstock later this month (Oct13).

The Since U Been Gone hitmaker's slimmed down look has little to do with fitting into her Alice Temperley gown - she's keen to have a healthy pregnancy.

She explains, "I wanna be doing the best I can for that kid and giving it the best shot right off the bat, coming from a healthy body.

"I would never do that for myself, but I'll do it for a baby, of course."
