The 32-year-old – who rose to fame as part of Girls Aloud – was once known for her love of partying and checked into rehab in 2011 for 'alcohol dependency and depression'.
But now Sarah has admitted the continuous clubbing was purely because she was bored.
She told Fabulous magazine: "A lot of [the partying] was just boredom and I was living in London, going out with a DJ [Tom Crane], and I think that just became a way of life. I think being busy is good for me, you know?
"When I’m not busy, that’s when I get bored, and I’m like: ‘Ugh!’ I need stimulation. I’m your typical hyper sort of girl who always needs, I dunno, something.”
“It really, really is. And it’s about time! My 20s were all heartbreaks and hangovers.”
Singer Sarah also poked fun at herself, adding: "I used to think I was Liam Gallagher, flicking the Vs at the camera, thinking I was rock 'n' roll."
These days Sarah's got plenty to be keeping herself busy with. As well as recently confirming that her Corrie contract as been extended, she's about to release her debut solo single Threads.
