After the girl-band decided to take a break from music, Sarah plunged into acting.
She recently starred as a schoolgirl alongside Rupert Everett and David Tennant St Trinians 2: The Legend of Fritton's Gold but is now aiming higher.
The leggy blond says she needs to work on her skills but would love to do some 'action stuff', Star Magazine reported.
"I'd be good as the kind of character that Grace Jones played in 'A View to a Kill' – a bad Bond girl!
"I don't see myself doing the glamour stuff. I'm kind of edgier", she said.
Despite her bandmate Cheryl gaining chart success as a solo artist and winning over the nation as an X Factor judge, Harding says she proud, not jealous.
"We all took this break and you don't do that without having an action plan. And that's what Cheryl's plan was."
