It pays to work for Posh and Becks

David Beckham and his wife Victoria have treated their mums to a top of the range Audi each to thank them for babysitting their four children.

The couple splashed out 100,000 pounds on two Audi A4 models, as a token of appreciation for how much Jackie Adams and Sandra Beckham have stepped in to care for Brooklyn, Romeo, Cruz and Harper, since the family moved to London from Los Angeles in January, the Mirror reported.

With the former footie star in Paris for much of the year and Victoria busy with her global clothing range, the grandparents have been helping so the couple didn't have to leave the kids with a nanny.

The mums have been on hand to help out at the A-list couple's rented mansion in West London, despite Jackie living in Hertfordshire and Sandra in Essex.
