Victoria Beckham suffered a panic attack and almost walked off stage ahead of the Spice Girls reunion gig at the Olympics closing ceremony.

Singer-turned-fashionista Beckham took to the stage on the last night of the London 2012 Games on Sunday (12Aug12) and turned to calming bandmate Emma Bunton as they made their way to center of the stadium in traditional U.K. black cabs.

During an interview for Britain's Heart FM radio station, the star praised Bunton for her approach, saying, "I was in the taxi with Emma before we started and I nearly just got out of the car. I was so nervous. I felt sick and Emma was so amazing. Honestly, that's how you know a real friend. If it wasn't for her, I would not have been out there."
