Kylie Minogue sent fans into a Fever with her performance at the 2014 iTunes festival.

The pop princess, in the midst of her Kiss Me Once UK tour, opened her show at London's Roundhouse lying on a giant lips sofa, wearing a red latex dress and feathered headdress before she sang Les Sex.

Her 90-minute set, which featured five costume changes, included songs from her new album Kiss Me Once as well as her well-known back catalogue of hits such as Spinning Around, Step Back In Time, On A Night Like This and Can't Get You Out Of My Head.

Kylie showed off her figure in a glittering array of skin-tight outfits including a black leotard, black sequinned bodysuit and latex corsets, which she teamed with a number of knee-high boots and high heels.

And the 46-year-old Australian singer jokingly told a fan off for asking her for an autograph during her energetic set.

"There's always one (who says), 'Can you sign my CD?' Have you seen what I'm wearing? I can barely hold the mic," she quipped.

"I can do many things in this outfit but that's not one of them," she added.

Overwhelmed by the applause, Kylie later admitted: "Honestly what did I do to deserve this?

"This crowd is 'wow'. You know the words better than me," she said.

And speaking to those who watched the live stream of her gig, featuring a spectacular light show, she added: "We miss you. We love you and we wish you were here on a night like this."

Kylie, who ended her set with All The Lovers, satisfied fans when she returned to the stage for an encore, performing Into The Blue and The Locomotion.

"This is such a beautiful venue. I've loved playing to you," she said. "Tonight is a special occasion," she added.

Scottish classical violinist Nicola Benedetti and Ed Sheeran will perform in coming days, before tenor Placido Domingo brings the month-long festival to a close on September 30.
