The 38-year-old singer - who formed one fifth of the chart-topping girl band along with Geri, Victoria Beckham, Emma Bunton and Mel C - is back in the recording studio to work on new music and is hoping her close pal will join her on a track.
She told The Sun newspaper: ''I'm definitely doing new music before the end of this year because I've just recorded three hot, hot singles. I'm having dinner with Geri so we will be talking about a collaboration.''
Mel enjoyed moderate solo success away from the 'Wannabe' hitmakers, including number one single 'I Want You Back' featuring Missy Elliot, but she has largely focused on reality TV judging roles since the band's split in 2000, most recently working on the Australian version of 'The X Factor' and 'America's Got Talent'.
Mel and Geri's collaboration would follow in the footsteps of bandmates Mel C, 39, and Emma, 37, who recorded a cover of 'I Know Him So Well' from the musical 'Chess' for Mel's 2012 album, 'Stages'.
The Spice Girls were a global phenomenon in the mid-to-late Nineties, spawning three albums, a movie and their own line of dolls.
Despite their success, Geri, 40, left the group in 1998, but the five-piece later reunited for a greatest hits tour in 2007 and again for a one-off performance at the London 2012 Olympics closing ceremony in 2012.
He also slapped a jet-lagged Taylor Hawkins.
The acclaimed performer had just cancelled touring due to a battle with cancer.
