The news comes a day after the Duchess returned to Instagram under the account @meghan.
Her first post showed her dressed in white, running on an overcast beach, to write 2025 in the sand, before dashing past the camera laughing.
Her second post shared the trailer for her upcoming show.
In it, she is seen making food in a home kitchen, shopping for flowers, and laughing and eating with friends.
“I’m going to share some little tips and tricks… and how you incorporate these practices every day,” Meghan says in the trailer’s voiceover.
“We’re not in the pursuit of perfection… we’re in the pursuit of joy,” she continues.
In one scene with others, Kaling says “this is probably one of the most glamorous moments of my life,” making Meghan burst into laughter.
Chefs Roy Choi and Alice Waters are also among the guests in the series.
“Everyone’s invited to create wonder in every moment,” the text of the trailer says.
Meghan’s husband Prince Harry even makes a brief appearance, with the two embracing as they hold drinks on a sunny outdoor patio. One of the couple’s dogs, Guy, also has a starring role.
