Victoria Beckham has come to blows with her mother-in-law, according to a new report.

The former Spice Girl – who is staying in LA while David plays another season with AC Milan – fell out with her husband’s mother Sandra – who was babysitting the couple’s sons Brooklyn, Cruz and Romeo – when she decided she wanted to return to London.

A source tells Britain’s Daily Mail newspaper, “Victoria had been house hunting 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.”

Victoria’s spokesman added, “Victoria never leaves her children for more than a week. The dates had already been organized with Sandra.”
