We knew the Spice Girls were close but we didn't know they were this close.
Mel B has been telling all about a sexual encounter with her bandmate Geri Horner, claiming that the pair slept together and "giggled about it" afterwards.
The 43-year-old made the revelation on an episode of Piers Morgan's Life Stories, nodding when the host asked if she had ever slept with Geri. Mel went on to say that "She is going to hate me for this because she is all posh in her country house and her husband, but it’s a fact. It just happened and we just giggled at it and that was it. We were best friends.” She added that she only had sex with Geri once.
Mel and Geri will be joined by their bandmates Mel C and Emma Bunton when the Spice Girls take to the stage at Croke Park on Friday May 24.
