Tributes continues yesterday to Girls Aloud member Sarah Harding who died from cancer aged 39.
The singer revealed last August that she had been diagnosed with breast cancer, which had spread to other parts of her body.
Her mother Marie announced the death on Instagram on Sunday and described her "beautiful" daughter as "a bright shining star".
Harding was part of Girls Aloud with Cheryl Tweedy, Kimberley Walsh, Nadine Coyle and Nicola Roberts from their formation on TV show Popstars: The Rivals in 2002.
Coyle posted a photo of Harding smiling broadly on Instagram and said she was "absolutely devastated" by the news.
She added: "I can't think of words that could possibly express how I feel about this girl & what she means to me!!
"I know so many of you will be feeling this way. For now I'm sending so much love to you!!!"
Roberts yesterday shared a series of photos of them together during Girls Aloud's early years and wrote: "I'm absolutely devastated and I can't accept that this day has come. My heart is aching and all day everything we went through together has raced round my mind.
"Especially this last year since her diagnosis, as hard as the year has been, our new memories are strong in my heart."
Sharing a black-and-white portrait of Harding on Instagram, bandmate Cheryl wrote: "Although we knew this day would arrive I am somehow still feeling at a loss for words that our stunning, unique, crazy, quirky, kind and soft-hearted girl has departed.
"As I try to navigate my way through these painfully strange and horribly unfamiliar waves of disbelief & finality I am experiencing, I wanted to extend my condolences to all of our GA fans.
"We were like an extended family for so long and we know so many of you by name."
She added: "I love you Sarah... farewell.
"Sarah Nicole Harding forever in our hearts."
Music manager Louis Walsh, who helped create Girls Aloud on ITV show Popstars: The Rivals in 2002, said he would remember Harding with "great fondness".
In a statement, he said: "It's just sad she has gone too young. She was always fun and the life and soul of the party".
