Curtis Pritchard and Maura Higgins have soured since they announced their split back in March last year.There’s been a LOT of mudslinging and shade-throwing between the former Love Island couple, especially after Curtis moved on with dancer Amber Pierson – although they’ve since split – and Maura went public with fellow Islander Chris Taylor.Tensions arose once again last week when it came to light that Curtis takes aim at his ex in a stand-up comedy routine he filmed for new Channel 4 show
