Margot celebrated her 31st birthday last weekend with a star-studded birthday party by turning her home into ‘Casa Amor’ like the Majorcan villa on the show.

The Wolf Of Wall Street star has long-been candid about her love of the UK reality show and proved herself to be a true fan by throwing the themed bash, where she was joined by ex-Home and Away actress Samara Weaving.

Looking incredible, Margot posed at the forefront of a snap with her pals while sporting a tiny pink bikini as the rest of the revellers took to the pool and got to work on replicating the Mallorcan villa of the show.
