Kate Middleton’s ready to have a new sister-in-law! The 35-year-old pregnant Duchess of Cambridge stepped out on Tuesday at The Foundling Museum in London, just one day after the news broke that her brother-in-law, Prince Harry, and Meghan Markle had confirmed their engagement.

Kate, who is currently expecting her third child with Prince William, looked beautiful in a black and white polka dot dress and red heels. 

Speaking with reporters at the event, Kate was quick to dish about Harry and Meghan’s engagement news.

“William and I are absolutely thrilled. It’s such exciting news,” Kate said (via BBC). “It’s a really happy time for any couple and we wish them all the best and hope they enjoy this happy moment.”

Once inside the museum, Kate, who has a background in art history, viewed some of the paintings. She also spent time with local children from the Argyle Primary School.

The Duke and Duchess were some of the many family members and friends to wish Harry and Meghan well on their engagement. Watch the clip below for more from the royals!
