Frankie and Wayne, who have a nine-month-old son together, got hitched at a swish ceremony at Woburn Abbey in Buckinghamshire.
Rochelle Humes, Una Healy, Vanessa White and Mollie King were all spotted looking suitably glamorous ahead of the wedding as they enjoyed a drink in the sun with their partners.
Rochelle’s husband Marvin was also in attendance, and they also brought along their daughter Alaia-May.
Una Healy was also joined by her husband Ben Foden and their daughter Aoife.
Sadly, photographers didn’t get manage to get a snap of the bride, while her bandmates - who usually love sharing updates on Instagram - didn’t post any snaps from Frankie’s big day.
