And now, with just months to go until Little Mix delight fans by touring the UK, rumours are swirling as to who could be supporting the girls.
If you are a fan of American band Fifth Harmony, then this news will really excite you! After the band announced their hiatus in 2018, members Lauren Jauregui, Ally Brooke, Dinah Jane and Normandi all went solo, with the girls releasing some major hits.
But now, it's rumoured that Ally could be joining LIttle Mix on tour, after her manager liked a fan tweet which translated as, 'There are rumours that Ally will open the LM5 Tour shows in Europe and the UK.'
Although nothing has been confirmed by either artist, the news was greeted well by both sets of fans, with many expressing their excitement for the upcoming tour.
