Meghan, Duchess of Sussex, honors Clare Waight Keller in surprise awards appearance

Meghan Markle, the Duchess of Sussex, surprised guests at the British Fashion Awards last night, as she made an unexpected appearance to honor her wedding dress designer, Clare Waight Keller.

After praising the fashion industry in her "new home of the UK," she named Keller, Givenchy's artistic director, as British Womenswear Designer of the Year.

Actress Rosamund Pike was initially scheduled to present the award. But after reading out the finalists, she welcomed a "special guest" to join her. Markle then appeared in a black one-shoulder Givenchy dress to rapturous applause from the star-studded London audience.

She described Keller as a "British designer leading on the global stage with vision and creativity, but also with incredible kindness," before announcing her the winner of the prestigious award.

Other celebrities from across the entertainment world were also in attendance at London's Royal Albert Hall, including Brooke Shields, Rita Ora and Robert Pattinson.
