Katy Perry had an awkward wardrobe malfunction at Radio 1’s Big Weekend when an energetic dance move showed off a bit more than she’d bargained for.

The Roar hitmaker was wearing a silver sequinned minidress with a matching blazer for the high-energy performance on stage in Hull.

She teamed her metallic look with white sneakers and long, dangling earrings, which bounced all over the place with Katy’s moves.

But it was when she squatted down for a more intimate moment with the audience that the malfunction happened – and she ended up giving the crowd an eyeful of her enormous white pants.

The 32-year-old has had a busy week, having also performed a gig at London’s Water Rats in front of a tiny crowd of 90 people on Thursday night, where she reminisced about her debut performance in the UK at the same venue nine years ago.

Speaking about her audience growing up too, she told the crowd: “If you’re not having great sex yet, in your thirties it’s going to be AMAZING.

“Ican’t speak for those of you in your forties but I’m sure it’s better… it’s fun, consensual and intimate.”

The singer recently released her innuendo-ridden single Bon Appétit and – in case anyone hadn’t quite picked up on what she was alluding to with her lyrics – Katy confirmed: “That’s what Bon Appétit is about, loving that beautiful thing. Just accepting it, now it’s so much fun.

“I used to be able not to hug people, it was really sad. Now I just want to hug everyone.”

Katy – whose new album Witness comes out on June 9 – split from actor Orlando Bloom in March, after dating him for almost a year.

Orlando, 40, slept with a waitress at London’s Chiltern Firehouse hotel, who was subsequently sacked. In her twenties, Katy married lothario Russell Brand and dated John Mayer.

Also at the gig, Katy revealed she’s been off the booze since January, although earlier in the night she pulled pints for new Capital breakfast show host Roman Kemp as she celebrated his new role at the radio station.

Earlier this week, Katy said she would happily end her feud with Taylor Swift – who her new single, Swish Swish, is not so subtly about – saying: “Honestly, she started it and it’s time for her to finish it. I’m ready for that BS to be done.”
