And Closer was on hand to witness all the shenanigans as we were served up Laurent Perrier alongside the bride to be and her party pals at the swanky China White enclosure.
Frankie, 25, who is set to tie the knot to footballer beau Wayne Bridge, 33, later this summer was joined by her Saturdays band mates Vanessa, Mollie and Rochelle, as well as family and friends.
But we're not sure how much of the rowing action they got to see as they were served up a delicious three course meal, followed by ice lollies, and copious amounts of wine, before they partied the night away as Pete Tong hit the decks.

The bride to be wowed in a tight red number by The Kooples, ensuring all eyes were on her, but she was sure to have been a little red faced when she realised she wasn't the only reveller sporting that very same dress.
But the stunning star took it in her stride as she told us she was really enjoying her special day and posed for pictures.
Frankie accessorised with a sparkly bride to be badge and sipped from a matching champagne flute before later being dressed up by friends in a veil and sash.
There was one Saturday missing out on all the fun, however. Una was noticeably absent from celebrations and remained tight lipped as to why on Twitter.

Meanwhile, we also bumped into our old Made In Chelsea favourite Hugo Taylor, who was showing off his range of swish sunnies.
The reality star - who enjoyed a stint in the I'm A Celeb jungle - helped us pick out the perfect pair as he said he was missing his mate Spencer Matthews who is still living it up in New York with the MIC cast.
We also caught up with Hugo's gorgeous girlfriend Natalie Joel, who told us she's over the moon that the pair have just got back together after a brief break-up.
The model looked effortlessly chic in a floral Topshop dress as she revealed she's busy working on her own swimwear collection.
Watch out, Kimberley Garner.
