Holly Willoughby and Emma Bunton once shared a “girl kiss” on a night.
Spice Girl Mel B revealed her bandmate Baby Spice had snogged the This Morning presenter and admitted she had confronted Willoughby with the gossip on Celebrity Juice.
Mel B told Heart Breakfast radio: “Emma Bunton, she’s a right good old gossip that one. She knows everything about everything right?
“I did that with Holly Willoughby because she told me the night before that they had a night out and had a little bit of like a girl kiss and then I was on the panel with Holly Willoughby and I went ‘Oh you and Emma you snogged didn’t you last night?’ she said ‘Why would you say that out loud?’ And then they aired it.”
Scary Spice - who earlier this year upset bandmate Geri Horner by claiming the pair had shared a night of passion back during the Spice Girls heyday - insisted she had no regrets about revealing her friends’ secrets.
She said: “I’m just very honest I can’t help it. Hence my show, Brutally Honest. Boom get that right in there.”
Kelly Brook, 39, who was hosting the radio show also revealed: “I tried to snog Holly once and she didn’t go there.”
Willoughby, 38, has three children with husband Daniel Baldwin while Bunton, 43, has two children with her partner of 21 years Jade Jones.
Mel B has previously pushed Willoughby to confess to having slept with a woman on Celebrity Juice.
Willoughby replied: “No, no, no. I haven’t.”
Host Keith Lemon persevered, asking: “Have you ever kissed the sweet lips of a lady?”
Willoughby asked: “What are you getting at?” and then repeated, “No.”
Mel B interrupted: “Don’t lie! Your voice has gone really high.”
