Leona, who won series three of The X Factor in 2006, is swapping the stage for the big screen in her first film role.
It was first announced in September last year that Leona would be starring in the flick chick, which was first called Holiday! before being renamed Walking On Sunshine.
The 29-year-old 'Collide' singer, who plays the character Elena, joins the likes of comedienne Katy Brand, Sense & Sensibility actor Greg Wise and Being Human actress Annabel Scholey in the feel-good musical.
The synopsis of Walking On Sunshine reads:
"Set to the music of popular hit songs from the 1980s. A beautiful coastal village, present day Italy. After a whirlwind romance, Maddie is preparing to marry gorgeous Italian Raf, and has invited her sister Taylor to the wedding. Unbeknownst to Maddie, however, Raf is Taylor's ex-holiday flame, and the love of her life..."
Walking On Sunshine hits cinemas on 13 June 2014.
