(CNN) The Spice Girls are reuniting - apparently minus one.

Emma "Baby Spice" Bunton, Geri "Ginger Spice" Halliwell Horner, Melanie "Mel C" Chisholm and Melanie "Mel B" Brown announced their United Kingdom reunion tour Monday on the official Spice Girls Twitter account.

The four appeared, without "Posh Spice" Victoria Beckham, in a spoof video sharing the news of the tour. They will be joined by a special guest, singer Jess Glynne.

The group split in 1998 after becoming one of the UK's biggest girl groups ever.
