Paltrow: Martin isn't a baby-sitter

Hollywood star Gwyneth Paltrow has hit out at claims she bosses rocker husband Chris Martin around.

The Coldplay frontman has been left holding the couple's seven-month-old daughter Apple while Paltrow promoted her recent movie Sky Captain and the World of Tomorrow, which hit cinemas in the US and much of Europe last year, but has yet to be released in Australia.
