She's preparing to tie the knot with footballer fiance Wayne Bridge in a romantic ceremony later this summer.
And Frankie Sandford proved that when you're a member of a chart-topping girlband, just one hen party simply isn't enough.
The 25-year-old singer enjoyed her second celebration of her upcoming nuptials on Saturday when she was joined by The Saturdays bandmates Mollie King, Rochelle Humes and Vanessa White in the Chinawhite enclosure at the Henley Regatta in Henley-On-Thames, Oxfordshire.
Here come the girls! Frankie Sandford proved that when you're a member of a chart-topping girlband, just one hen party simply isn't enough as she enjoyed her second celebratory bash on Saturday afternoon
But while the bride-to-be had her nearest and dearest around her for the most part on her special day, fifth member Una Foden was nowhere to be seen as the girls partied the evening away.
Frankie and the gang certainly dressed to impress for the upmarket occasion, rocking a series of primary colours as they posed for a group photograph outside the tent.
Leading the way, Frankie - who gave birth to baby son Parker in October 2013 - showcased her slim post-baby body in a striking scarlet minidress and tan peep-toe heels.

Vanessa opted for a vibrant yellow hue, looking like a ray of sunshine in a semi-sheer lace detail skater dress, which she teamed with towering cobalt stilettos.
Rochelle slipped into a pretty mint green pleated skirt as she posed with her pals, and made sure to show off her slim waist in an unusual plunging grey peplum top with cut-out detailing.
Towering on a pair of strappy nude heels, the What About Us hitmaker completed her look by wearing her chocolate brown locks tumbling around her shoulders in a glossy mane of curls.

Completing the quartet, Mollie also opted for summer pastels; rocking a sensible baby pink blouse, a retro-inspired white full skirt and nude patent heels.
And the girls certainly seemed to cause the usual hen party carnage, in spite of their sophisticated surroundings.
Posting numerous pictures on their Instagram pages, the gang seemed to have found a new friend in the form of a chap who fell asleep near their table.

Vanessa wrote alongside one hilarious snap: 'Don't fall asleep next to a hen party.'
Meanwhile, Una remained silent about her whereabouts via her Twitter page.
Frankie - who enjoyed her first hen party celebration in Ibiza last month - is preparing to tie the knot with Reading FC star Wayne later this summer.
The happy couple have been dating since 2010, and welcomed baby son Parker into the world together in October 2013.

But rather than stress herself out with the details of her big day, Frankie is remaining relaxed about her impending nuptials.
She recently told OK! magazine: 'I'm not a Bridezilla! I'm being very laid-back about it actually. I probably feel like I should be a little more stressed than I am, but I'm just excited.'
Wayne, 33, popped the question back in April 2013 - shortly before the pair announced they were expecting their first child together.

Speaking about her beau's romantic proposal, Frankie told Capital FM at the time: 'Wayne took me to a hotel and he got my dogs involved.
'I didn't know my dogs were there and they came in in little bride and groom outfits. And Pixie had the ring around her neck on a ribbon.
'He's been acting so weird that when he left to come back in and do the whole proposal thing, in my head I was thinking, "Oh no, we've become one of those couples that can't make conversation at dinner".'
Cooling off: Vanessa and Rochelle refreshed themselves with an ice lolly as they took a break from the fun
