Mel B. admitted to having a steamy fling with Geri Halliwell of the Spice Girls during their heyday in an interview with Piers Morgan. Here's more from TooFab:
"She's going to kill me and so's her husband," Mel laughed after admitting to the rumors.
But, Mel insists, it was just a one-time encounter. "She's going to hate me for this because she's 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."
She also noted with a smile, "She had great boobs."
"And hopefully when Geri gets asked that, which hopefully she will after this, she won't deny it," Mel said. "Because it was just a fun thing."
When Morgan tried to dig in and ask how many times they'd been together, Mel shut him down hard. "Stop it, you pervert!" she said. "We were best friends. It just happened. Have you ever done that?"
