Gwyneth Paltrow went "all out" to celebrate her son's birthday at their Los Angeles home.

A source told Us Weekly magazine: "Everything took place in the backyard.

"Colourful tables were set up everywhere, and hula hoops and balls for the kids to play with."

The guests - 20 of Moses' friends, plus a number of his nine-year-old sister Apple's pals - were greeted by big blue ombre faded balloons spelling out the birthday boy's name, plus another in the shape of a number eight.

The children also got the chance to design their own t-shirts, with the airbrushed creations including each guest's name and an image of their choice.

Gwyneth spared no expense when it came to food either, with a number of trucks, including gourmet hot dog vendor Dogtown Dogs and Los Angeles' favourite India Jones serving up dishes including hot dogs topped with Fritos and street food like samosas, curry and tacos.

It is unclear whether Coldplay frontman Chris was at the party.
