Gwyneth Paltrow's March to Madonna's

A casually dressed Gwyneth Paltrow runs into Madonna‘s New York City apartment on Monday.

The nanny also followed Gwyneth into the apartment holding David Banda, Madonna‘s youngest son.

The 35-year-old actress has joined with Claudia Schiffer, Christy Turlington and Yoko Ono to sign an open letter to the G8 first wives to push the work of the White Ribbon Alliance. These prolific women and mothers are supportive for the charity which focuses on preventing women dying in childbirth, reduced infant mortality rats and improved hospital conditions for mothers and babies in developing countries.

P.S. Madona‘s brother Christopher Ciccone claims Madge shared a steamy kiss on BFF Gwyneth Paltrow at a New Year’s Eve bash for designer Donatella Versace. All the details will be published in his upcoming unauthorized autobiography, Life With My Sister Madonna.
