Fellow Spiceys Geri Halliwell ( 40), Mel B (37), Emma Bunton (36) and Mel C (38) had all bounded up the red carpet together earlier in the evening.
Ginger, Sporty, Scary and Baby beamed and waved enthusiastically, clearly thrilled that their iconic 90s hits were being revived for a new audience.
The in-demand designer arrived late at the premiere and moved up the red carpet sporting her signature sullen pout.
Posh also decided to give the after show party a miss, prompting speculation that she has no interest in the Spice Girls.
All five stars took to the stage to thank writer, Jennifer Saunders.
While the rest of the girls jumped about in excitement, Victoria looked somewhat embarrassed.
Staring sheepishly at the ground, she very much gave the impression that the whole thing was beneath her.
And in a way it is. Since the girls split, Posh has gone on to bigger and better things.
She's now one of the world's most successful fashion designers and, along with her footballer husband, has most of Hollywood's A-List celebs on speed dial.
The rest of the girls have had moderate success as judges on various reality TV shows, have had a handful of modest hits and are clothing ambassadors for mid market brands including Next and Argos -- not exactly Hollywood glamour.
The shift in their careers and relationships was also reflected in their outfits choices.
While the rest of the girls went for OTT glitzy looks, Victoria kept things simple.
The mum-of-four looked demure in a pair of black cropped Isabel Marant trousers, a plain white shirt from her own label and a plum wool jacket draped over her shoulders.
Geri's outfit -- a powder blue ball gown -- had plenty of wow factor and looked like something from a fairy tale.
Both Mel B and Emma opted for floor length dresses with thigh high splits, while Sporty Spice showed off her toned and tanned legs in an olive green mini dress.
The new musical, which critics are already comparing to smash West End hit Mamma Mia, tells the story of a girl band who pursue stardom on a reality TV series.
