Roberts, who took to the stage with former band mate Cherly Cole over the weekend, also expressed her heartbreak on social media.
"I’m absolutely devastated and I can’t accept that this day has come," she wrote on Instagram.
"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.
"There are so many things to say and at first it felt to personal to put them here and then I remembered that there are so many other people grieving her too.
"A part of me or us isn’t here anymore and it’s unthinkable and painful and utterly cruel."

Kimberly Walsh shared a photo of herself and Harding on Instagram, saying "this hurts so bad".
"To wake up and know that you are really gone is too much to bear.
"Hearing your infectious chucklw was one of my favourite things in the world. Your fire burned so bright and you loved, lived and laughed so hard.
"Sending love and strength to everyone who is grieving today. My heart is broken."

On, Cole wrote on Instagram: "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.
"I wanted to make sure you knew just how much your love and continued support meant to Sarah through her most vulnerable times."
