"Ms. Markle is grateful to everyone who has followed her social media accounts over the years", the palace statement said.
According to People.com, her profiles on both sites disappeared on Tuesday, shortly after undertaking her second official royal engagement with Prince Harry in London. "However, as she has not used them for some time she has taken the decision to close them".
Meghan's final post on Instagram was posted in April 2017 after she shut down her personal blog, The Tig. Instead, updates about their lives and careers are posted on one set of accounts, run by Kensington Palace.
She was met by cheers from a crowd waving both United Kingdom and US flags when she and Harry attended their first official event as an engaged couple in December in Nottingham. It's where Prince George and Princess Charlotte's births were first announced, and just yesterday, when they shared photos of Charlotte ahead of her first day of preschool. Last year, she also ended her partnership with Canadian department store Reitman's for a fashion line.
