Regarding the rumours about modelling, Marnie said in a Rolling Stone interview: "I'm not really sure where the 'model' information has come from; perhaps something was mentioned in a very early press release. I've never really done proper catwalk. I only ever did a few bits and pieces along with a couple of graduate shows as a favour to friends. I am, after all, only 5' 6" [168 cm]. Far too tiny to be a model. Plus, I look kind of weird, not in that coveted model alien way. Just in a plain weird way!".[
