Fifth Harmony will be making their Summertime Ball debut on 6th June - but what could they learn from previous Ball artists about putting on the perfect show?
Everyone knows that Wembley Stadium literally shakes with the power of Jessie's killer vocals - if the Fifth Harmony girls can throw out a high note or two like this, they're onto a winner! Picture: Danny North
Because who DOESN'T love batting a giant inflatable duck around with 80,000 other people at Wembley? Large inflatable props are a must! Picture: PA
These ladies definitely know how to stand out from the crowd with their costumes - their 2014 Summertime Ball looks were the most talked about outfits of the day. Who doesn't like a good feathered shoulder accessory, eh? Picture: PA
Willow Smith may have sung about whipping your hair back and forth but no-one does it quite like Rita Ora! A bit of hairography always goes down well with an 80,000 strong crowd. Picture: PA
Cheryl made one heck of an entrance back in 2012 as she delighted fans with a surprise performance at the Ball, arriving on stage by being shot out of the floor in a skintight rainbow jumpsuit. Casual! Picture: Andy Squire
Swifty's never afraid to 'Shake It Off' - and she always pulls out her finest moves for her Ball performances. As long as you're having a great time, the crowds will be too! Picture: PA
Usher kept the Ball crowd screaming by bringing out Biebs during his set in 2011. Justin joined Usher during his final song, 'OMG', and proved that a great special guest will guarantee your performance will go down in Summertime Ball history.
The Vamps are never afraid of a challenge, and they can always be found getting up to mischief backstage. Last time they performed at one of our Balls, they aced the Chubby Bunny Challenge - and there will definitely be some treats in store this year too.
There's never been an act that has had quite so many people dancing along in sync, but PSY managed to get 80,000 people doing his Gangnam Style dance in 2013. Time to start choreographing that routine, ladies! Picture: Danny North
