Looking ABBA-fab! Jo O’Meara and Anthea Turner lead the red carpet stars as they help celebrate the fifth birthday gala performance of Mamma Mia! The Party

Jo O’Meara and Anthea Turner channeled their inner Bohemian Island style as they stepped out in Greek-inspired ensembles for the fifth anniversary gala performance of Mamma Mia! The Party on Wednesday night.

The 45-year-old S Club star looked on trend in a ’90s-inspired look as she wore a tight white top with cutouts on the chest as she headed to London’s O2 Arena.

She teamed her long-sleeved top with blue skinny jeans, embellished with gold studs around the pockets and ankles.

The blonde beauty completed her look with classic white heels, which made her look even taller.

Joining her on the blue carpet was 64-year-old TV presenter Anthea, who showed off her timeless beauty. She wore a blue and white peasant blouse with Greek-inspired patterns on the sleeves.

The experience includes a multi-course Mediterranean dinner with dishes inspired by Greek cuisine.

The dinner is interwoven with the performances, so the show unfolds around the guests as they eat.

The cast, who sing and dance throughout the tavern, perform the songs live.

Mamma Mia! The Party was originally created by ABBA member Björn Ulvaeus and premiered in Stockholm, Sweden in 2016.
