Madonna kicks off her “Sticky & Sweet” world tour at the Millennium Stadium in the Welsh city of Cardiff on Saturday. Her husband, film director Guy Ritchie, and children Lourdes, Rocco and David were in the audience of 40,000 strong.

The 50-year-old pop icon was dressed in a black one piece outfit designed by Givenchy, with matching knee-high boots, fishnet tights and a sparkly cane.
