Queen Elizabeth is a modern day woman, even at the ripe age of 90.

Her Majesty took to Twitter — yes, Twitter — on Tuesday to thank the world for the outpouring of birthday messages she's received since celebrating her birthday in April. However, the birthday celebrations have continued.

"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 wrote.

The Kensington Palace's official Twitter actually clarified in a subsequent message that the message was indeed sent by the boss herself, not a public relations person.

"This tweet was personally sent by Her Majesty The Queen," the message said.

A mere five hours after her tweet, it had been liked 14,000 times and retweeted over 5,000 times.

And, for those who may have been skeptical, the palace shared an image of the moment actually taking place, with the Queen sitting at a writing desk and dressed in a magenta floral gown, writing the message on an iPad. Gold-plated designs surround her in the room.

"The Queen has tweeted to thank all who have sent messages of goodwill on social media for her Birthday #Queenat90," the caption of the photo said.

That photo was liked more than 6,000 times and retweeted nearly 3,000 times.

The Queen's personal message is only the second time she's sent out a tweet. Her first ever tweet was sent during a visit to the Science Museum in October 2014 to officially launch their Information Age exhibition.

"It is a pleasure to open the Information Age exhibition today at the @ScienceMuseum and I hope people will enjoy visiting. Elizabeth R.," she said at the time.

The widely-loved monarch has been embracing technology recently, even being influential in redesigning the Palace's website in April.

"She's always been conscious of improving the ways we communicate the work of the royal family," a palace source told People magazine at the time. "She's been an enthusiastic supporter of social media since the early days of it."

Last year she even said she chats with her grandkids via Skype!

Queen Elizabeth is proving that technology isn't just a young person's game.
