In a separate post, she added: ‘Wide awake at 6am and thought I’d scare my country neighbors with some inappropriate eye make up on my morning walk.’

Lady Mary and Robbie spent time in New York in December, with the socialite sharing a handful of snaps of their adventures on Instagram. 

It is thought she arrived back in Los Angeles at the start of the year.
