Charlotte Casiraghi, niece of Prince Albert and soon his bride-to-be Charlene Wittstock, is fixed to steal the 'other' Royal Wedding show when her uncle weds his longtime girlfriend this weekend.

Pippa Middleton, Kate's younger sister, famously grabbed the spotlight at the April wedding of the Duke and Duchess of Cambridge, turning many a head in a figure-revealing white wedding dress. Her fame now rivals her sister's , despite being a relatively unknown commoner before the wedding.

Charlotte Casiraghi, on the other hand, is no stranger to international attention - she is the granddaughter of the late Princess Grace and Prince Rainier of Monaco, and is fourth in line to the throne of Monaco. She is an avid equestrian and sometimes attends official royal engagements with her uncle, Prince Albert.

Drop-dead gorgeous and filthy rich, the camera often finds Charlotte although she certainly does not seek it out. No doubt she will be the focus of worldwide attention this weekend as she attends her uncle's wedding festivities.

Charlotte, who is the daugher of Princess Caroline of Hanover, has an estimated worth of 5.7 billion.

According to the Herald Sun, reporting from a Le Figaro story, Charlene will have six bridesmaids, but it is unclear if Charlotte will be one of them.
