Prince Harry recently praised his fiance’s taste in music, saying he could vouch for her “good tunes”.But the Spice Girls have a long record of mixing with royalty, with Geri Halliwell famously kissing Prince Charles on the cheek and appearing to pinch his bottom. Today in #GirlChatLive, Mel B shares if she is going to Meghan Markle and Prince Harry’s wedding, and if the SPICE GIRLS ARE PERFORMING!! pic.twitter.com/Wx5geXuR7G— The Real (@TheRealDaytime) February 27, 2018 Throwing her cue cards in the air, her co-hosts screamed, ran around the studio and exclaimed: “Yes they are performing! Yes!”“I need to go,” said Mel B. “I’m going to be fired.”Asked for details on what the wedding invitation looked like, she added: “It’s getting too personal to describe it.It was proper. I’m not saying any more.”Kensington Palace did not wish to comment on the claims. It is understood that invitations to non-performing wedding guests have not yet been posted. Appearing on American television chat show The Real, Mel B was asked whether she knew any fellow Britons who had been invited to the wedding.Nodding, she confessed: “Yeah, I’m going… I don’t know if I should’ve said that!”Pressed further by co-hosts, she continued: “Well us five Spice Girls… why am I so honest?”The singer, who gained a reputation as the most outspoken of the group in its heyday, appeared to struggle to say nothing as she was asked outright whether they would be performing, looking down with a smile and shaking her head in mock frustration. In November 1997, Prince Harry made his first public appearance after his mother’s funeral at their charity concert in South Africa with his father.Sandy Henney, then press secretary to the Prince of Wales, has previously recalled asking the Spice Girls to meet the young Prince, reminding them that he had recently lost his mother.Then, Mel C and Victoria Beckham “fussed over him”, while Emma Bunton kissed him on the cheek, leaving the Prince “like the cat who’d got the cream”.In April 1998, band members were invited for tea at Highgrove hosted by Prince Charles and his younger son.Prince Harry’s wedding to Meghan Markle will take place in Windsor Castle on May 19th, with guests and performers as yet unconfirmed by Kensington Palace.
