The girl group performed on both the Arena Stage and the Sony Xperia Access stage, and they also nabbed backstage passes to the Mahiki Rum bar and Virgin Media's Louder Lounge, an exclusive hospitality area set up in Hylands Park.
And it looks like singer Amira McCarthy indulged in a spot of pampering while she was there!
Not only did the Louder Lounge include a spa area where Mark Hill hair, Eylure lashes and Elegant Touch nails were situated, attendees could also visit the Glitter Lips stand for their very own, well, glittery lips!
Amira made her pout stand out by opting for a bright pink shade which she paired with flawless skin, perfectly-arched brows and heaps of fluttery lashes.
Other celebs who also added some sparkle to their smackers at the event included X Factor star Amelia Lily and 'Kisses For Breakfast' singer Melissa Steel. We've also spotted Bella Thorne rocking a shimmery pout in the past!
Fancy getting the look? We love this super-glam bubblegum pink shade, £12.50 from Beautyboulevard.co.uk. It comes with glue which you paint onto your lips, before dipping the applicator provided into your pot of glitter and dabbing over the top.
Alternatively, if you'd prefer to keep things slightly more low-key try a lipgloss packed with glitter particles instead. MAC Dazzleglass in Extra Amps, £17.50, is perfect for adding a touch of disco ball dazzle to your look, without going OTT!
