IT seems Katie Holmes is someone Victoria Beckham can rely on when she needs a friend to look after her children at the last minute. After reportedly falling out with her mother-in-law over babysitting arrangements, it was Katie Holmes' turn to take charge yesterday. The actress was seen out and about in Los Angeles with two-year-old daughter Suri and Victoria and David's youngest two boys, Cruz, four, and Romeo, six. Along with another helper, thought to be a nanny for the Beckhams, they all ventured out in Santa Monica to go to The Children's Arts Studio. Suri looked cute as she held Katie's hand, dressed in a blue-spotted dress and red-striped cardigan, complete with her favourite accessorry - a cuddly toy. Meanwhile Cruz and Romeo cut a cool look in jeans and shirts and looked excited as they headed into the centre. Perhaps Victoria had asked Katie to babysit as a favour after falling out with her mother-in-law Sandra recently. The fashion designer was reportedly forced to rush back from Milan last week, where David is on loan to A.C. Milan, after her mother-in-law Sandra decided she wanted to go home to London. Sandra was babysitting her three grandchildren, including Brooklyn, 10, while Victoria was househunting in Milan. But a source revealed: 'Victoria had been househunting in Milan, but then Sandra decided she wanted to be at her daughter's birthday, so Victoria had to fly back early. Sandra and Victoria had a row.' - DM
