Chart star Rita Ora dazzled a crowd of tens of thousands in a sequinned mesh dress as she performed at Wembley Stadium.
The singer shared a bill with her ex-fiance, DJ and producer Calvin Harris, at the annual Capital FM Summertime Ball.
Ora rose from a stage in the centre of the London stadium shrouded in a red hooded cape before casting it aside to reveal her skimpy minidress.
Her two-song set included hit single How We Do (Party) as she performed with a troupe of dancers.
Almost matching her outfit for brevity was fellow performer Jessie J, who wore a jewelled white minidress.
The former coach on BBC1's The Voice performed tracks such as Price Tag while showing her once-familiar black bob hairstyle is back following many months with a shorter blonde style after shaving her head for Comic Relief.
Other acts at the event included Enrique Iglesias, Australian pop act 5 Seconds Of Summer and Clean Bandit.
Brit Award-winning star Ellie Goulding performed earlier in the day, singing hits such as Burn and Goodness Gracious.
Many in the crowd had got into the party spirit by daubing their faces and arms with fluorescent body paint.
The event will also feature performances from Miley Cyrus and David Guetta.
Cheryl Cole got the crowd to perform a Mexican wave around the stadium midway through her set, which included hits such as Call My Name and Fight For This Love.
The former Girls Aloud star was appearing just a day after putting a new generation of pop hopefuls through their paces at an audition for the next series of ITV's X Factor.
The singer wore a white cropped satin jacket and matching miniskirt - so short that she kept flashing her underwear - trimmed with the words Crazy Stupid Love, the title of her new single.
US superstar Pharrell Williams, wearing faded denims and a stylish squashed hat, played some of the recent huge hits with which he has been involved, including Blurred Lines, Happy and Get Lucky.
Controversial singer Miley Cyprus - who famously appeared naked in her Wrecking Ball video - was uncharacteristically modestly dressed, unlike her dancers.
While she wore a silver crop top and skirt dotted with plastic flowers to twerk on stage, her dancers wore denim hotpants and a layer of sequins on their otherwise bare breasts.
Despite it being a family show, her dancers waved giant joints and she swore repeatedly during the show, telling fans to "Make some f****** noise".
She also spat water on the audience before telling them: "I've never played Wembley before so I'm going to stay on this stage as long as I can."
The US former child star still managed to get some of the biggest cheers of the night as she skipped off stage with a dwarf dancer.
