David and Victoria Beckham have treated their mothers to a £50,000 sports car to thank them for babysitting.

The superstar couple have shown their gratitude for Jackie Adams and Sandra Beckham for looking after their children - daughter Harper, two, and sons Brooklyn, 14, Romeo, 11, and eight-year-old Cruz - so they didn't have to get a nanny.

A source told the Sunday People newspaper: ''David and Victoria aren't flash with money because they know the value of it, but they wanted to show their enormous gratitude for the help their mums have been since they returned to England.

''Managing their careers and four children is not easy at all, so they feel so lucky that their parents have stepped in to ease the load.''

Jackie and Sandra are said to be ''really touched'' by the gift - a top of the range Audi each - and were pleased to help the Beckhams so they can still be ''hands-on'' with their children.

The insider added: ''David and Victoria have never been keen on getting nannies. They have always been hands-on with the kids, but sometimes everyone needs a bit of help from their own parents.

''Jackie and Sandra are really touched with their presents. They couldn't thank them enough.

''They are over the moon that David and Victoria are back in the UK and both women love seeing more of their grandchildren.''
