After shedding the pounds, Bea has been spotted out and about at a number of red carpet events, showing off her newly svelte figure.
Last Friday we spied the Princess attending a charity ball with mum Sarah Ferguson.
And yesterday she wowed again, this time on the arm of boyfriend Dave Clarke at the Reuben Foundation Haiti Fundraiser, held at exclusive venue Altitude 360, one of the London's tallest buildings.
Looking glam and glossy, the young royal opted for a chic LBD and ruffled blazer combo, teaming it with a satin clutch and towering Louboutin studded heels.
The proud princess beamed for the cameras - clearly thrilled with her new figure - and showed no signs of worry over mum Sarah Ferguson's recent embarrassment.
Bea mingled with other guests throught the evening, including Holly Valance,the Ecclesone sisters and Richard Branson's children Sam and Holly.
