Mel C reportedly clashed with Geri Halliwell-Horner over her choice of white outfit at Mel's wedding, with friends of the newly married Sporty Spice said to be furious that her Spice Girls bandmate wore a colour traditionally reserved for the bride. Sources close to Mel C described the move as "unforgivable" and questioned why Geri could not "avoid white for once", suggesting long-standing tension between the pair resurfaced on what was meant to be Mel's big day.

Daily Mail columnist Katie Hind reports that friends branded Geri's wardrobe choice a "diva" moment, framing it as another example of friction within the group. The piece does not specify further details of the wedding itself, focusing instead on the reaction from Mel C's inner circle to Geri's outfit and what it reveals about the dynamic between the two Spice Girls.
