Princess Maria-Olympia and her father Crown Prince Pavlos of Greece had a joint birthday celebration last night and the theme? Prince and Revolution – how very appropriate! In one of the most elaborate birthday bashes, the two royals celebrated their 50^th and 21^st birthday respectively with the who’s who of fashion and society. Along with all the Greek royals Paris and Nicky Hilton, Tory Burch, designer Valentino and his cofounder Giancarlo Giammetti, Laudomia Pucci to name a few were in attendance at this glamorous affair.

And the beautiful princess wore a stunning Steven Khalil dress – uh obsessed!
