Talking about all her most recent runway moments, she told us that she's getting increasingly concerned about her 'resting bitch face'.
'I'm like, "Don't have such a blank stare on your face."'
'I've got resting bitch face so I'm trying to think about happy thoughts now when I model,' she continued.
'I'm trying not to look like I'm about to murder someone.'
Wearing a beautiful Julien Macdonald tasselled dress and Altuzzara boots, she said she was worried about turning around in case her bottom might be on show.
