Prince Harry gets by with a little help from the Duchess of Sussex.

A heavily pregnant Meghan Markle made a surprise appearance by joining her husband at a WE Day event in London's SSE Arena Wednesday. People magazine reported the thousands of students and teachers in attendance went wild for Markle, 37, who is expecting her first child with Harry, 34.

WE Day, a worldwide initiative, aims to inspire young people to make positive steps toward social change.

Markle’s baby bump was on full display as she opted for a more casual ensemble of slim black pants, a matching top and a navy blue blazer. The former American actress completed her look with soft, loose waves.

People shared the event marked the second time Harry has spoken at a We Day event. When he first did, five years ago, his then-girlfriend, British actress/model Cressida Bonas, joined him and watched from the stands.

The publication added Harry was speaking in his capacity as President of Queen Elizabeth II’s Commonwealth Trust. According to his office, it connects young leaders who are leading “social purpose ventures around the world by giving them a platform that both funds their work, and shares and amplifies their ideas.”

“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,” Harry told a crowd of 12,000. “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. But don’t let them sway you.”

“Because you don’t need to hide behind your device to share your voice,” added the British royal. “You confidently voice your opinions because you can embrace them proudly.”

Harry also referred to Markle, noting that she “often reminds him” of “one of her favorite quotes by Martin Luther King Jr. — Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.”

After his speech, Harry then shocked a roaring crowd by announcing, “Alright, now I’m going to try to drag my wife on stage!” The children erupted into screams as a beaming Markle smiled and waved.

“Guys, I am with you and we are with you — now get to work!” said Harry.

Markle is due to give birth sometime this spring.
