The Saturdays night fever at new music festival in Birmingham

Singer Jessie J joined girl group The Saturdays,US star Neyo and band Mcfly to perform at the first ever Fusion Festival at Birmingham's Cofton Park.

It was also marked one of the final appearances in the region by boyband JLS who are to split up later this year.

The group made their penultimate Midlands performance minus band mate Oritsé Williams who was taking part in ITV's new dance show Stepping Out.

However the three remaining members Aston Merrygold, Marvin Humes, and JB Gill still put on an energetic display.

Their final gig in the area will be at the LG Arena in Birmingham in December as part of a goodbye tour.

At Saturday night's concert Marvin thanked fans for their support since the group first starred on X Factor five years ago.

Devoted fans Clare Daniels and Sophie Wallace, both aged 18, of Great Barr, were thrilled with getting the chance to see JLS perform.

"I'm going away to university so I don't think I'll get to see them on tour so when we saw they were performing we had to get tickets," said Claire.

Sophie added: "I've seen them three times before and we voted for them on X Factor so it is sad they are splitting up but the show was great."

Former judge on BBC talent show The Voice, Jessie J, headlined the event on the Saturday and braved chilly temperatures by bounding on stage in skin-tight black and white leggings and top.

She teamed the outfit up with gold earrings which showed off her short, platinum blonde hair, which she has kept cropped since shaving her head to help raise money for Comic Relief last year.

The athletic singer called on the audience to keep dancing to stay warm and even momentarily left the stage to blow her nose as temperatures fell to around 11C (51F) following a warm day.

But her headline set proved a real crowd pleaser as she effortlessly rolled through her catalogue of hits including Price Tag and Do It Like a Dude and latest single It's My Party.

The 25-year-old, who quit The Voice to concentrate on her singing career, was reflective throughout her hour and 15 minute set thanking fans who had flooded her with messages of support ahead of her new album launch.

She joked with one fan called Dave who appeared on the video screens and sang an impromptu song about him to the delight of the crowd.

Her set built to a rousing finale including versions of her hit singles Laserlight and Domino to send the audience home happy.

In total 21 acts took to the stage over two days at the event which was organised in aid of the Prince's Trust, with £5 from each ticket sale donated to the charity to help change young lives across the UK.

Danielle Smith, aged 19, from Edgbaston, Birmingham, had got tickets with her sisters 17-year-old Sarah and Daisy, aged 14, and enjoyed Union J and Mcfly.

"They are both our favourites and it's great to have them both at the same show," said Danielle.

"The festival has been really good and I hope it happens again next year."
