The music legend, who will join the Spice Girls on their long-awaited reunion tour later this week, was spotted partying the night away at a central London bash.
Teaming up with Virgin Voyages, the starlet dazzled as she attend an exclusive launch party for the brand in a [remove double space] floor-length white gown.
Shrink-wrapping her curves, the skintight gown let Geri flaunt her trim frame.
Teasing her sex appeal, the number featured a large slit up the left hand side allowing her killer pins to take centre stage.
Adding a touch of glamour, Geri opted for a pair of bejewelled open-toed heels.
She completed her look with a golden clutch.
Taking to Instagram to gush over her evening, Geri posted her red carpet look online along with the caption: “A special project coming!”
Last month Geri was left-faced after Mel B told Piers Morgan about a secret fling with Ginger Spice.
Speaking on his ITV show Life Stories, Mel spilled: “We were best friends. It just happened. It wasn’t a thing. It just happened.
“We just giggled at it and that was it.
“It just happens one time and then you talk about it and it does not really happen again.”
She added: “It was just that one time.”
