From poser to Princess: model Kendra Spears gets her Prince American supermodel Kendra Spears is set to become a Princess as she announces her engagement to Prince Rahim Aga Khan, eldest son of Aga Khan IV. Kendra Spears has been dubbed the 'mini Cindy Crawford' thanks to her brunette locks and a mole on her upper lip similar to that of famous supermodel - but now she's set to have a whole new identity: Princess. The 24-year-old American has become engaged to 42-year-old Prince Rahim Aga Khan, the eldest son of His Highness Aga Khan IV, the current Imam of Shia Ismaili Muslims. Although the fact that they were courting seems to have gone under the radar, the Aga Khan Development Network released a statement announcing their engagement on Friday, in which it is stated that "The couple will be married in a Muslim ceremony. The date of the marriage has not been set yet. The announcement was accompanied by official photographs of the couple in which Spears wears a conservative blue dress and flashes her large diamond ring. Spears later confirmed the news, tweeting "Thank you all for the kind tweets! We're very excited!:)  IN PICTURES: Models and their millionaire partners Spears was discovered when she won a Ford Models competition in 2008, she has since gone on to appear in countless catwalk shows and on covers for publications such as Vogue and Elle and in campaigns for the likes of Calvin Klein, Emporio Armani and Diane von Furstenberg.

It seems there's somewhat of a trend for beautiful women marrying into the family - Spears' betrothed is the product of his father's marriage to British model Sarah 'Sally' Croker-Poole, who was once considered one of the 12 most beautiful women in the world, while his grandfather, Prince Aly Khan, was once married to Rita Hayworth. If Spears follows the same protocol taken by her fiance's mother when she married into the family, she will likely take on the title of Princess as well as adopt an Islamic name and convert to the religion. It could also be assumed that she'll leave her modelling career behind to work alongside her husband, who is thought to be worth $800 million, in the family's numerous philanthropic ventures, although nothing has been confirmed.
