Girl Power has an end date.

The Spice Girls musical “Viva Forever!” will end its six-month run on June 29 at London's Piccadilly Theatre, said producers, citing poor ticket sales.

"We just can't make it work," said producer Judy Craymer -- who was behind Abba's global hit "Mamma Mia!" -- “Viva Forever! may be taking its leave for now in the West End but the legacy of Spice Girls will never fade."

The 2 1/2-hour musical written by Jennifer Saunders tells the story of an aspiring girl band who try to make it big on a reality TV show set to such Spice Girls hits as "Wannabe," ''Stop," and ''Who Do You Think You Are?" The show opened in November to promising advanced sales of some £4 million, or $6.2 million, but some critics said the performances lacked the personalities of the real Spice Girls, the Evening Standard notes. More than 200 unsold seats were available on certain nights, the BBC reports.

The Spice Girls have sold 75 million records worldwide. Emma “Baby Spice” Bunton said she was “totally gutted” when she heard the show was closing.

In a statement, the Spice Girls said "We want to thank the cast and all the fans for their support, and although Viva Forever! won't continue in the West End we are thrilled that the thousands of people who came to the show had as much fun as we did."
