PRINCE AZIM spared no expense for his 26th birthday this year (09) - inviting celebrity guests including Mariah Carey, Janet Jackson, Sophia Loren and Faye Dunaway for a lavish bash.
The Sultan of Brunei's son hosted the social event of the year at Stapleford Park in England last weekend (beg13Jun09) - and the stars turned out in full force to help celebrate his big day.
Hollywood legends such as Dunaway and Ursula Andress rubbed shoulders with Carey, model Jerry Hall, and singer Chaka Khan, who performed for the 230 guests.
The prince, fourth in line to the throne of Brunei, is said to be worth an estimated $22 billion (£13.5 billion).
