The Duchess of Sussex will mark the day with her husband Prince Harry at the wedding of his best friend Charlie van Straubenzee, who is marrying Daisy Jenks in Surrey.
Her birthday is also a special day for Prince Harry’s grandmother, the Queen, whose mother, the Queen Mother, was born on the same day win 1900.
But despite Meghan being forced to shut down her social media websites as part of Royal protocol, it seems we still may known what she is wishing for.
In her now-defunct lifestyle blog, The Tig, she has previously revealed she asks for “more surprises, more adventure, more opportunities to grow, more days filled with giggles and cheeky jokes, more delicious meals, and more inspiration, always more inspiration” every year.
Meghan Markle gave insight into her relationship with her mother Doria, revealing some advice she has provided her with for her birthday.
She wrote: “My mum always said that birthdays are your own personal New Year.
“Your own chance to make resolutions just for yourself and what you prognosticate for your year ahead.”
The Duchess also opened up about her birthday wish in 2014 in an essay for ELLE UK as she turned 33 years old, asking people to be “kind” and “challenge” themselves.
She said: “I am 33 years old today. And I am happy. And I say that so plainly because, well… it takes time.
“To be happy. To figure out how to be kind to yourself. To not just choose that happiness, but to feel it.
“So for my birthday, here’s what I would like as a gift: I want you to be kind to yourself. I want you to challenge yourself.
“I want you to stop gossiping, to try a food that scares you, to buy a coffee for someone just because, to tell someone you love them… and then to tell yourself right back. I want you to find your happiness.”
In her blog, The Tig, Meghan also opened up about her life following her teenage years, describing her 20s as “brutal” and how she always judged herself.
She wrote: “My 20s were brutal – a constant battle with myself, judging my weight, my style, my desire to be as cool/as hip/as smart/as ‘whatever’ as everyone else.
“My teens were even worse – grappling with how to fit in, and what that even meant.
“My high school had cliques: the black girls and white girls, the Filipino and the Latina girls.
“Being biracial, I fell somewhere in between. So every day during lunch, I busied myself with meetings – French club, student body, whatever one could possibly do between noon and 1pm- I was there.
“Not so that I was more involved, but so that I wouldn’t have to eat alone.”
Due too the closure of her social media accounts, it is unknown exactly how Meghan will spend her birthday privately on Saturday, but earlier this week, her first Royal birthday present was disclosed to the public.
Animal rights organisation PETA (People for the Ethical Treatment of Animals) has sent Meghan a vegan leather handbag by sustainable brand Alexandra K.
Elisa Allen, PETA Director, told OK! Online: “PETA believes this animal-friendly bag is absolutely perfect for the Duchess, as she is mostly vegan and cares about animals and the environment – in sharp contrast to the leather industry, which, in partnership with the meat trade, kills over one billion animals every year.
“Chances are that this gorgeous handbag will inspire the Duchess to embrace vegan fashion and leave all animal skins out of her wardrobe, as she’s already done with fur.”
