Jetsetter: Cheryl Cole performs at Radio 1's Big Weekend in Bangor, Wales, after flying back from Cannes, FranceIt's been a busy week for Cheryl Cole.
After enjoying film premieres at the Cannes Film Festival in France, Cole jetted back to the UK to play at Radio 1's Big Weekend in Bangor, Wales.
And going from showbiz royalty in Cannes to actual royalty in England, Cole had the opportunity to perform in front of Prince William and his girlfriend Kate Middleton, who made the most of the sunshine at the event.
Military: The singer wore a green parka jacket, metallic hotpants and boots for her setDressed in her usual military-style outfit of a parka jacket and hotpants, Cole belted out her most famous hits during her 25-minute set, as well as turning her hand to a cover of Owl City's Fireflies.
But it was Fight For This Love and Parachutes and 3 Words which were best received by the 20,000-strong crowd.
Before singing 3 Words, Cole - who duets with close friend and Black Eyed Peas star Will.i.am on the track - told her fans: 'Everybody that's in love in here today I want you to turn to your partner and sing this one.'
Cole wasn't the only act to cause a stir at the annual event.
Alicia Keys donned an unusual plunging harem-style outfit for her set on stage, during which she performed some of her most famous including Empire State of Mind
Shiny happy people: Alicia Keys wore an unusual black jumpsuit for the eventKeys's track, which pays tribute to the singer's hometown of New York, was recently reworked by the Radio 1 team to instead honour the landmark icons of North Wales ahead of the Big Weekend.
A spokesperson for the Chris Moyles show said earlier this week: 'We do a lot of parodies on the programme.
'And it's only fitting for us to do a special one ahead of our visit to north Wales this week.
'Since it's been played a lot of people have assumed that it's Alicia Keys singing, but it's actually a session singer.'

The singer recently gave an interview saying how much she enjoyed performing at festivals, explaining: 'I love festivals - the atmosphere of it and the crowd is always amazing.
'Being able to see other bands play and just hang out with everyone backstage, there’s a real sense of camaraderie.'
But while the crowd couldn't get enough of Florence & The Machine, their reactions were mixed to some of the other acts.
