Victoria Beckham has been blasted after reportedly refusing to do signings for her dVb range.

The Spice Girls star - who recently starred in a series of adverts for U.S. fashion designer Marc Jacobs - left Los Angeles fans disappointed after allegedly turning down the opportunity to promote the fashion collection in person.

Rihanna celebrated her 20th birthday with a cupcake fight.

The 'Umbrella' singer - who doesn't turn 20 until next Wednesday - was partying with friends including Kanye West and actor Wilmer Valderrama at Los Angeles' Les Deux nightclub when the food fight began on Tuesday night.
