The royal sisters and their mum joined forces with the 40-year-old rapper in Manhattan to mark the 14th anniversary of the attack of the World Trade Center.

The foursome, who were also joined by other celebrities, took control of the phones for the Cantor Fitzgerald Relief Fund in the hope of raising more money for the charity.

After wrapping up on the phones, Beatrice, Eugenie, Sarah and 50 - whose real name is Curtis James Jackson III - posed for a photograph together.

Princess Beatrice, 27, looked ravishing in a pastel blue below-the-knee skirt, a black long-sleeved blouse and a pair of sophisticate stiletto heels, while her sister Eugenie, 25, slipped into a navy blue floaty dress and little ankle booties.

Sarah, 55 - known as the Duchess of York - flaunted her incredible physique in a tight-fitted pencil skirt and military-style cropped blazer, while 50 looked dapper in a suit.

Other stars to join in the fundraiser included Pamela Anderson and Margot Robbie, who both manned the phones and attempted to raise more cash for the charity.

The Cantor Fitzgerald Relief Fund aims to distribute money to the victims of terrorism and natural disasters.
