And now she has experienced the life of taking part in an editorial fashion spread, Katie is desperate to continue in the world of fashion modelling.
She said: 'I've done Wonderland magazine, a spread and a cover, which will hopefully open up fashion magazines for me.
'Hopefully they'll see I'm still a good model with a story to tell and it'll be different to the weekly celebrity magazines.'
But then again, Katie has had experience shooting for fashion magazines in the past, as she was apparently handpicked by Anna Wintour to appear in the shape article in the 2006 edition of Vogue magazine.
And it was modelling that first shot her to fame, although it was a vastly different kind - glamour modelling.
