The 27-year-old posed for photographers at London's Royal Albert Hall in an elegant black dress with a plunging neckline and a thin strap around the neck.
This is the first time we see Amelia with such a spicy cleavage.
The dress had a long train and she complemented it with platform shoes and heels.
In her hands, the girl held a black clutch on a gold chain strap.

Lady Amelia wore a light make-up, accentuating her natural beauty, with her hair in a bun, leaving a few strands in the front.
And of the jewelry she wore a gold chain around her neck, the same bracelet and a ring.
Princess Diana's twin nieces, Lady Amelia and Eliza Spencer, were also present at the event.
The sisters wore dresses from Alberta Ferretti.
Amelia wore a black maxi dress and carried a clutch with scattered stones, while her sister wore a black and silver one, embroidered with small stones and matched a plain black clutch.
