Meghan & Harry Shine at NYC Mental Health Gala

The Duchess of Sussex took to Instagram to mark International Day of the Girl, sharing sweet clips of her little girl alongside an empowering message for young women everywhere.

Meghan shared a heartfelt Instagram post with a video of daughter Lilibet and a photo of the the two of them holding hands.

“To all the girls — this world is yours. Do everything you can to protect your rights, use your voice, support each other. We will do the same for you,” she captioned the photos.

“Go get ‘em girl! 🏃‍♀️ Happy International Day of the Girl,” the post concluded.

The post comes after Meghan and Prince Harry appeared in New York City on Thursday, Oct. 9, stepping out for the annual Project Healthy Minds’ World Mental Health Day Gala at Spring Studios.

The Duke and Duchess of Sussex coordinated in sleek black looks; Meghan in a tailored Armani suit and Harry in a classic black version of his own.

Meghan elevated her outfit with a chunky gold chain necklace, minimalist makeup and a chic ponytail.

The next day, Meghan shared a personal moment from behind the scenes of the gala on her Instagram account. The black-and-white video showed the couple laughing together backstage as Sylvie Vartan’s “Baby, c’est vous” plays in the background.

“Happy World Mental Health Day,” Meghan wrote over the clip, tagging her husband with the sweet caption, “…to the man who always keeps me laughing.”

Meghan Markle and Prince Harry spent time with a close friend in New York City after they were honored at a mental health event this week.

On Friday, Oct. 10, the duo squeezed in time for lunch with Serena Williams while they were in town for a series of scheduled appearances, PEOPLE can confirm.

Meghan, 44, Harry, 41, and Williams, 44, all dined at New York’s Soho House.

The tennis star and the Duchess of Sussex first met at the Super Bowl in 2010. When they crossed paths again in 2014, Meghan and Williams hit it off “immediately” and have been close since.

Earlier this week, on Thursday, Oct. 9, the Duke and Duchess of Sussex accepted the Humanitarians of the Year Award at Project Healthy Minds’ third annual World Mental Health Day Gala. The pair was honored for their digital safety and mental health work as co-founders of the Archewell Foundation.

“Working with families and young people to prioritize safety online has been some of the most meaningful work of our lives. As parents ourselves, we have been moved to action by the power of their stories and are honored to support them,” Harry and Meghan said in an earlier joint statement. “We’re proud to be long-time partners of Project Healthy Minds as we work together to shine a light on what remains one of the most pressing issues of our time.”

The couple, who share two children, Prince Archie, 6, and Princess Lilibet, 4, also attended Project Healthy Minds’ annual World Mental Health Day Festival on Oct. 10 alongside a slate of other stars, from Katie Couric and Carson Daly to Deepak Chopra and Sophia Bush.

Under the umbrella of the Archewell Foundation, Harry and Meghan established The Parents’ Network, an organization offering support for families whose children have been negatively impacted by social media, at an earlier World Mental Health Day Festival back in 2023.

Meghan also marked another achievement in New York City in May 2023, when she was recognized as a Woman of Vision Award honoree by the Ms. Foundation, appearing alongside Harry and her mother, Doria Ragland.
