The singer is showing some love for the group, which has announced a gig in Croke Park as part of its reunion tour.
The singer has shared this picture on Instagram of him wearing a t-shirt with #IWannaBeASpiceGirl written on it, but unfortunately this doesn't mean he'll be stepping in to replace Victoria Beckham on the group's tour.
Sam is just supporting the band's charity campaign, which is called Power Up and is in aid of Comic Relief, which is a UK initiative that aims to raise money for a wide range of causes every year.
