All five members of the iconic pop group - completed by Mel B, Victoria Beckham and Geri Halliwell - locked lips during their time together, and the former Sporty Spice has admitted her blonde band mate was her favourite.
Speaking to the Daily Mirror newspaper, she said: ''I've always been so drunk every time, it's hard to remember... But I would have to say Emma!''
However, Mel C explained she has only even kissed girls to be ''silly'' rather than because of any ''sexual'' feelings.
She added: ''I've never dated a girl but there's often been speculation, which I find quite funny. I've kissed girls but it's more being silly than anything sexual.
''There are so many hot girls out there but, actually, boy-wise, that question stumps me.
''I am so unimpressed. It would be quite nice to have someone to lust over but I really couldn't say anyone.''
She also explained the status of her love life, insisting she is ''completely single''.
She said: ''Setting the record straight, I am completely single. I've been having loads of fun, have met loads of new friends, my social circle has massively widened and if a chap wants to take me out for dinner...''
April 2021 may have been one of the coldest in 60 years, but there were still enough hot releases to warm our hearts and fuel our fires.
