Victoria Beckham celebrated her 40th birthday at a luxurious spa on Thursday (17.04.14).

The fashion designer, who flew to Los Angeles late last month, was whisked away by her husband, David Beckham, and their four children, Brooklyn, 14, Romeo 11, Cruz, eight, and Harper, two, for a relaxing day of pampering.

A source told E! News: ''Victoria is spending her birthday today quietly with her family. They have travelled out of state to somewhere quiet and relaxing and are enjoying a spa vacation.''

The former Spice Girl posted a series of photographs from her childhood on her Twitter and Instagram profiles as she toasted the milestone.

She also shared an image of her wearing shorts from her serene location, with the caption: ''Good morning! Special day with my beautiful babies and wonderful husband, I love you all so much x vb''

A source previously revealed that the brunette beauty didn't want a huge bash and plans to celebrate at an intimate dinner party with some of her closest friends, including her hairstylist Ken Paves, Eva Longoria, Kate Beckinsale, Gordon and Tana Ramsay.

The insider said: ''She really doesn't want a big party contrary to what many people think, those kind of ostentatious events just aren't her style.

''She is in Los Angeles on holiday and as David insisted on doing something, they've settled on a lovely dinner party with some of Victoria's LA-based friends and they'll do another one when they return to London. They also have a few special days planned out with their children in California, who are on their Easter holidays from school, and that is what Victoria is looking forward to most.''
