The gorgeous singer was joined by friends - including sister Victoria - for a girls' only party on Friday (23 May) ahead of her wedding to footballer Wayne Bridge.
Frankie, 25, looked amazing as she partied at Ocean Beach Ibiza's Official Opening Party, and appeared to be having a great time basking in the sunshine and sipping drinks at the star-studded venue.
Lucky for some!
While we're pretty sure nobody at the exclusive club wouldn't know who Frankie is, her girlfriends all donned matching black bikini bottoms with the word 'hen' on them just to draw attention to Frankie's big event!
We also couldn't help noticing Frankie was in white while all her pals were in black - rather similiar to Kim Kardashian's mini-bachelorette party in Paris last night, where she rocked a bejewelled silver Balmain frock while her girlfriends all sported dark colours.
Well, she should stand out on her own hen do!
The 'What About Us' singer became engaged to Reading Football Club player Wayne, 33, in April 2013, shortly before announcing they were expecting their first child together.
Frankie gave birth to son Parker in October 2013.
