Kate Middleton's little sister Pippa and brother-in-law Prince Harry are determined to make her 30th birthday one to remember.
Party planner Pippa, 28, and Harry, 27 - who loves a night out - are expected to be throw Kate an 80s themed celebration.
'Pippa and Harry have been in the thick of it and have recruited a bunch of friends to help,' reveals an insider.
'The guests have been sent Save The Date cards and told that it will probably be in London.
'Given the people organising it you can be sure it will be a brilliant bash.'
It seems that for one night only, Prince William's wife Kate will be given the chance to relive her party times at the University of St Andrews.
'In many ways this is going to be Kate's last chance to let go like she did back in the old days,' the source tells the Daily Star, 'when she and William first met.'
