18 years ago there was just one question to ask a potential friend: which Spice Girl is your favourite? We can't believe this was almost two decades ago - it's making us feel old!
Break out the (sugar-free) jello and (raw fruit) cake - it's Victoria Beckham's 40th birthday!
The slender singer-turned-fashion-darling will no doubt be celebrating the milestone with David (who puts the 'hubba-hubba' in 'husband') and their four children - Brooklyn, Romeo, Cruz and Harper.
Perhaps she'll be chowing down on a frozen grape or two as a treat, or feeling reflective about her past - 18 years of which have been spent in the public eye.
To celebrate, we look back at some of Posh Spice's best bits: from pouting to pregnancy, performing to proposal.
