She may be 90 years old, but Queen Elizabeth can keep up with the best of them, particularly on social media.
The monarch took to Twitter — yes, Twitter — to thank people who have sent her birthday wishes over the past few months.
“I am most grateful for the many digital messages of goodwill I have received and would like to thank you all for your kindness. Elizabeth R,” she said in a tweet posted to the royal family’s official account.
The R" stands for "regina," Latin for queen, and is part of how the monarch officially signs her documents.

And in case anyone questioned the authenticity of the post, the @RoyalFamily account followed it up with another tweet: "This tweet was personally sent by Her Majesty The Queen.”
It then issued another post, one that included a photo of the queen at a desk composing the message.
The queen reached her landmark 90th birthday in April, but the milestone has been observed on numerous events since then.
Queen Elizabeth, the longest reigning British monarch, has helped guide the royal family through the digital age through its use of social media, which has allowed the Duke and Duchess of Kensington to regularly share updates about issues they support as well as photos of their young children, Prince George and Princess Charlotte.
Queen Elizabeth, however, has not been active on social media. The last time she tweeted was also the first time. On Oct. 24, 2014, she tweeted a post supporting the opening of the Information Age gallery at London's Science Museum.
