Wearing a black plunging suit, and her hair in a top bun, Sarah oozed confidence as she spoke to Emma Willis before entering the doors.
She told Emma she was ‘bricking it’ but wanted people to see the real her.
“I never thought I would do this. I just want people to see where I come from. I came from reality TV so why not go back and start over.”
In an exclusive interview with The Sun just hours before she entered the house, Sarah promised she was a changed woman.
She said: “I played up to a caricature when I was in the band, always pouting in photos and being the entertainer.”
And she’s planning on being on her best behaviour in the house, adding: “I won’t be drinking much, I’d like to keep a level head, stay sane and avoid dramas.”
