Harper Beckham all grown up as she steals the show at Victoria's 50th birthday bash

Harper Beckham was the star of the show at her mum Victoria's glamorous 50th birthday party this weekend, as the 12-year-old wore a stunning champagne silk dress for the occasion.

Spice Girl-turned-fashion designer Victoria gave her fans a glimpse into her extravagant celebrations as she partied with pals and her family, posing with her husband David, 48, and their children for several snaps before celebrating in London.

The couple's four children attended the lavish bash, with eldest sons Brooklyn, 25, and Romeo, 21, wearing matching ties to their dad. Meanwhile, their youngest son Cruz, 19, stood out in a white suit.

A number of Victoria's A-list friends also attended; including Tom Cruise, her former Spice Girls bandmates, and TV chef Gordon Ramsay and his wife Tana. The dazzling event took place at Oswald's, a private members club in London's Mayfair.

Harper, the youngest of the Beckham brood, paired her spaghetti strap gown with white open-toed heels and a matching box clutch bag. Her golden hair was straightened as she wore a very natural brush of make-up.

She smiled alongside her mum for a snap outside the venue, with Victoria looking stunning in a mint green gown with a sheer skirt and ruched detail around her waist. Despite having to use crutches due to a foot injury, she still matched the ensemble with a pair of white stilettos.

Ahead of the event, Victoria took to Instagram to share some family photos of them all looking chic in their suits and stunning dresses taken at their London home. The caption read: "Can't wait to celebrate with my friends and family! I love you all so much."

Victoria later shared a clip from the celebrations on Instagram, showing her enjoying a dance and singing with former bandmates Geri Horner, Mel B, Mel C and Emma Bunton. She posted the clip with the caption: "Best night ever! Happy birthday to me! I love you all so much. #SpiceUpYourLife. ".

They were a huge part of her life and they shared so much together."

The source further added: "They were special days, and so, of course, to have them there to mark her 50th was just wonderful for her. It made everything so perfect."
