Drew, 41, stepped out wearing a stunning Tory Burch embellished gown on the same day 34-year-old Kate was seen in the dress. While He's Just Not That Into You star Drew was attending the 2016 ASPCA Bergh Ball in New York, the Duchess and husband Prince William were dining with the Himalayan Kingdom's Dragon King and Queen.
Both women wore the dress differently. Drew kept things simple and teamed it with a pair of Christian Louboutin heels, but Kate oozed elegance by accessorising with sparkly gold earrings and a gorgeous orange shawl.
In New York Drew was being honoured with the Compassion Award for her outstanding contributions to animal welfare. She looked radiant on the orange carpet, and posed happily with charity president Matt Bershadker and a seriously cute dog called Murray.
The Duke and Duchess were on the penultimate stop of their trip where they visited Lingkana Palace in Bhutan before they return to India on Saturday.
Kensington Palace tweeted a montage of photos from Kate and William's time in Bhutan, and added: "Thank you Bhutan for a magical day in Thimphu today! #RoyalVisitBhutan".
If you want to make like the Duchess and Drew, the Tory Burch dress will set you back more than £1,000 – but, going on how amazing they both look, it might be worth the price tag.
