It was confirmed earlier this year that former Girls Aloud singer Sarah, 33, will join the ITV soap next month – and she's understandably nervous.
Speaking to the Daily Mail, she said: "I am my own worse critic so I might be watching from behind a cushion. You can't please everyone, you win some you lose some!
"But I would like to think I did my character justice."
She might have reservations about her reception, but Sarah already has a lot of acting work under her belt.
During Girls Aloud's hiatus from 2009-2012, Sarah appeared in BBC film Freefall and the St. Trinian's sequel, The Legend of Fritton's Gold.
But pop fans shouldn't worry: Sarah isn't turning her back on music completely and is working on new material.
She continued: "It's good to be back with a bang. There is so much going on right now but it's great to be busy. I'm really looking forward to what's to come."
