The entire Sussex family is celebrating Duchess Meghan amid the launch of her Netflix series, With Love, Meghan, today.

The duchess flew to New York City Monday night to surprise a group of longtime fans (from her days running her lifestyle blog, The Tig) at a screening of her show ahead of its release. And while husband Prince Harry and their kids, Prince Archie, 5, and Princess Lilibet, 3, stayed home in Montecito, California, they sent her a sweet gift to mark Meghan's milestone.

On her Instagram Story, the duchess shared a photo of a beautiful bouquet of pink roses and other pink and white flowers that she received from her family. With it, came a message written on pink paper. "Congratulations mumma! We Love your show, and we love You!" It read. Written with different-colored markers, the note was signed: "Lili Archie Papa xx."

Harry makes a romantic cameo to dote on Meghan in the last episode of the series' first season, which dropped today. But Archie and Lili do not appear on camera, as Meghan and Harry like to keep the kids out of the spotlight, and have said that they try to raise them to have as normal a life as possible.

To maintain her family's privacy, Meghan also decided not to film her show inside their Montecito home. (Learn more about the set here.) "I wanted to protect that safe haven," she told People. "We're a close-knit family, and I love those moments -- putting Lili down for a nap, having lunch together, having sacred time together at the end of the day. Our kitchen is where Mama just cooks for the family, and with a crew of 80-plus people, that's a lot of people to have in your house!"
