The American singer wore a glamorous floor length custom made green emerald dress by Walter Mendez dress.

The dress had cut aways that flashed some cleavage at the top and a thigh-high slit. The detail of the dress also included purple feathery puff sleeves.

With her hair in a ponytail, she accessorised her look with gold dropping earrings from Lorraine Schwartz and OFIRA jewels and a silver limited edition Alexander Wang x Judith Leiber clutch bag.

To finish it off, she wore what appeared to be bronze-shimmery Christian Louboutin shoes.

The mum of three was knock out on the red carpet.
