Spice Girls Reuniting for Queen Elizabeth's Diamond Jubilee

The biggest girl group of the '90s is making a comeback! Spice Girls singer Melanie Brown revealed the band will be reuniting this summer during a recent interview on Australian TV -- but contrary to reports, it won't be for the 2012 Olympics opening ceremony.

"I think the Queen's Jubilee concert is the event I'd be looking at more closely for that to happen," the 36-year-old said. Realizing she revealed too much, the singer quickly changed the subject. According to The Sun, Brown told TV crew members backstage: "I am going to be in such strife for saying that. It's all so totally bloody top-secret still."

The "Scary" musician and her bandmates -- Victoria "Posh" Beckham, 37, Geri "Ginger" Halliwell, 39, Emma "Baby" Bunton, 36, and Melanie "Sporty" Chisholm, 38 -- last performed together during a reunion tour that kicked off in 2007.

"I'm always down for a Spice Girls reunion," Brown said. "I love the Scary hair and platforms. Any time of day or night I'll be there."

To mark 60 years of Queen Elizabeth II's reign, the Diamond Jubilee will take place on June 4, 2012. The group will perform in front of the royal family, including Prince William, 29, and Kate Middleton, 30.
