True blue-blooded royalty was in attendance on the biggest night in Hollywood's calendar.
Monaco's Prince Albert and his beautiful wife Charlene added an extra touch of class to the evening and fitted in perfectly with the stars.
The new princess was chic in a high-necked gown with an open back.
Natural make up provided the finishing touch to her elegant look.
Her white gown was part of one of this year's biggest red carpet trends, with many leading ladies opting for gowns in cream and ivory.
Attending the Oscars would have been a poignant event for Prince Albert, as his late mother, Princess Grace, was an Academy Award winner.
