But there was nothing sweet about Keisha's outfit as she arrived at London's Scala music venue, showing off a lot of front in a daring dress, as they celebrated their return to the stage.
The girls were all dressed in black for their comeback gig - 12 years since they last played live together.
Mutya flashed her tats, whilst Siobhán complimented her red hair with an emerald green top.
The girls received a four-star review from the Metro, who wrote: "MKS boast powerfully distinctive vocal harmonies, but they also have an exceptional camaraderie with their fans."
The Evening Standard said: "Freak Like Me had lost none of its smutty swagger and when new single Flatlines segued into Push The Button, the band’s future and past combined thrillingly."
And The Independent gave MKS five-stars, calling the gig "thrilling and emotional, with the sense of a wrong turn finally righted".
