It's time to find out whether Girl Power is still going strong, with the premiere of a new stage musical based on the songs of the Spice Girls.
The members of the 1990s girl group - Baby, Sporty, Scary, Ginger and Posh - are expected on the red carpet for Tuesday's opening night of "Viva Forever" at London's Piccadilly Theatre.
The musical uses Spice Girls songs including "Wannabe" and "Spice Up Your Life" in a tale of four friends whose bond becomes strained when their band enters a TV talent show.
It's a pop confection with heavyweight credentials. The show was written by comedian Jennifer Saunders, co-creator of celebrity-skewering sitcom "Absolutely Fabulous."
The producer is Judy Craymer, who produced stage and screen versions of the hugely successful ABBA musical "Mamma Mia!"
