Kate is thought to be in the city on business, but is expected to fly to Majorca this weekend with her boyfriend Jamie Hince for a dose of rest and relaxation.
Topshop billionaire Sir Phllip Green is reportedly paying £100,000 to fly her out for the luxury holiday after she complained of feeling 'a bit run down'.

A butler, masseuse and beauty therapist will be on hand to accommodate their every whim.
Adds the source: 'They also get a boat so can disappear to any cove.'
