The lineup is star-studded.

Cheryl, Nadine Coyle, Nicola Roberts and Kimberly Walsh will come together later this year for a gala honouring the memory of their late bandmate Sarah Harding. Sarah passed away last year after being sick with breast cancer. Now, the band members will raise money for cancer charities through an event set to take place on 8 October in London. The gala, which is titled The Primrose Ball, will be held at the Londoner Hotel and will feature performances from a number of singers including Olly Murs, Years & Years' Olly Alexander, The Kaiser Chiefs' Ricky Wilson and The Pretenders' Chrissie Hyde. Cheryl, Nadine, Nicola and Kimberly will serve as hosts, while Fearne Cotton will present. There will also be a charity auction hosted by Jonny Gould to raise money for the Christie NHS Foundation Trust and Cancer Research UK. Speaking ahead of the event, the Girls Aloud members said that their hope for the event is that it will "raise a huge amount of money that will hopefully prevent other people finding themselves in the same terrifying situation Sarah found herself in." Earlier this year, the group honoured Sarah's memory at the Race for Life in Hyde Park. Ahead of the event, Cheryl spoke about her grief. "It doesn’t feel like she’s gone at all," she said at the time. "To be honest, I’ve never experienced or anticipated this grief." Nadine Coyle, meanwhile, spoke about how she was "in denial" over the loss. "This time last year we were actually hanging out," she said. "We all met up last year. She was there and we were talking and she didn’t even seem that sick." "I was in denial the entire time and was the friend that was 'Oh, it’s gonna be all right’, you know, I was completely in denial right up until the day she passed."
