The Shakespeare in Love star was in Portofino, Italy with husband Chris Martin and their two kids when she turned 40 on 27 September.

It seems Paltrow wanted a third bash on home soil - so she threw a dinner party for a host of her celebrity friends in New York this week.
Paltrow and Beyonce were joined by Diaz, comediennes Chelsea Handler and Kristen Wiig, supermodel Christy Turlington, actor Ethan Hawke and director Steven Spielberg at Elio's restaurant in Manhattan.
Her actress mum Blythe Danner also showed up for the get-together.
