Once an actor has played the same character for a while, it can be tricky to view them in any other way.
But did you know she's also had a very different role? Back in 2002, Kellie was once the girlfriend of fictional character Ali G. Kellie actually made her feature film debut in the comedy role when the movie was made based on Sacha Baron Cohen's TV character. At the time, she'd already made her mark in acting, having worked as a child actress by starring as Little Cosette in the production of "Les Miserables" in London's West End.
As well as this, the actress bagged the runner up spot in the 13th series of Strictly Come Dancing. She may also be familiar to you as she starred in popular ITV series Bad Girls back in 2002.
