With minimal make-up and a dowdy smock top on, Katy didn't appear to be celebrating her unrivalled earnings.

She tossed her hair over on one shoulder with no particular styling and later tried covering up her high profile appearance with a stripey scarf.

Katy and her friend seemed to be engaged in a lengthy catch up that saw them focus attention purely on each other.
