Prince Harryhelped inspire a group of young people to make positive steps toward social change on Wednesday — with a little help from an exciting guest: his wife!

Meghan Marklejoined her husband as Harry appeared at the worldwide initiative calledWE Daywith thousands of students and teachers, who went wild for the duchess.

Wearing blackRag & Bone maternity jeanswith a matching, bump-hugging top, the mom-to-be topped the look off with a navy blazer and styled her hair in loose waves.

The event marked the second time Harry has spoken at a WE Day event. When he first did so, five years ago, his then-girlfriend Cressida Bonasjoined him and watchedfrom the stands.

Addressing the 12,000 gathered, Harry said on Wednesday, “If we look at the world we’re living in, I know it can feel challenging sometimes — but your role is to shine the light.” “Every day you are inundated with an overexposure of advertising and mainstream media, social media and endless comparisons, distorting the truth, and trying to manipulate the power of positive thinking,” the prince continued. “But you don’t let them sway you.
