Spice Girl Emma Bunton was given a special treat by her bandmates at a gig on Sunday - after they presented her with a lavish birthday cake on stage.

The singer celebrates her 31st birthday today, but chose to celebrate the occasion a day early with fans and her fellow Spice Girls at London's O2 Arena.

Melanie Brown, Melanie Chisholm, Geri Halliwell and Victoria Beckham gave their pal the tasty treat - which was shaped like a castle and covered in marshmallow and candy decorations - during the show, which was watched by Bunton's mom, her boyfriend Jade Jones, and the couple's five-month-old son Beau.

The Spice Girls' two-month residency at the O2 Arena ends on Tuesday, after which the band travels north to continue the U.K. leg of The Return Of The Spice Girls tour in Manchester, England, before returning to the U.S.
