It was Sarah who won Celebrity Big Brother 2017 on Friday night, beating Amelia Lily in the final vote.
Now she's in talks to release her own autobiography, covering her time in Girls Aloud and up to her Celebrity Big Brother victory.
A source told the Daily Star newspaper: "Her autobiography will chart everything up to her stint in the house. Then she can start afresh with her life."
During her time in the house, Sarah spoke frequently about her times in Girls Aloud and her bandmates.
She admitted to not being in touch with most of them and spoke candidly about her struggles in rehearsals.
And Sarah confessed she felt "lost" when they split back in 2013, admitting to missing her days on stage.
Meanwhile, her appearance on CBB proved controversial.
Despite winning on Friday night, Sarah left to a mixed reaction including boos from the live audience.
"I'm in shock," she told Emma Willis after leaving. "It's been a bit of a tough ride. I was so out of my comfort zone, so many big personalities.
"I needed a new chapter and start a fresh. I just thought what better way to get out of my comfort zone and to show the viewers at home I'm just a normal girl. I've gone through a whole spectrum of emotions.'
She added: "I want to say thank you to who voted. I honestly didn't believe this would happen."
Sarah continued: "It was really difficult to adjust to the new environment. The main reason was to show everyone that I was just Sarah. I've been through ups and downs. I'm so grateful, it's made me stronger and tougher.
"Once I got more adjusted, I was definitely feeling more settled. It's made me a stronger person, I've grown a thicker skin, I am an anxious character that's just me."
Celebrity Big Brother airs on Channel 5.
