Texts From Hillary, a hot new Tumblr featuring a sunglasses-clad, all business Hillary Clinton checking her cellphone on a military plane, got a guest submission from an unexpected source on Monday: Secretary of State Clinton herself.

"sup adam. nice selfie Stace :-)" reads Madam Secretary's post. "ROFL @ ur Tumblr! g2g — scrunchie time. ttyl?"

Stacy Lambe, one of the site's co-creators, confirmed that the post was indeed from the Secretary herself.

"Her staff reached out to us with the submission yesterday," says Lambe. "And we just met with her this afternoon. She was very delightful and thought kindly of us. I can tell you, her staff just thought the whole thing was great."

Need more proof that's actually from Clinton? Here you go. And there's this, too — the post signed by the Secretary, thanking the team for the "LOLZ."

What was Clinton's favorite TextFromHillary so far?

"She mentioned being a fan of the Ryan Gosling post," says Lambe. (And who can blame her? He saves strangers from oncoming traffic, after all.)

Texts From Hillary is built around photos of Clinton checking messages on her cellphone aboard a military C-17 aircraft. The blog features Clinton responding to texts from politicians and celebrities in various awesome and hilarious ways.

The site was the brainchild of Adam Smith and Stacy Lambe. It has been spreading across the web like wildfire. No wonder Clinton's team would want to get involved — doing so creates a boatload of positive press as rumors of a possible Hillary 2016 presidential bid continue to float around the political sphere.

The original photos were taken by Reuters' Kevin Lamarque and Time's Diana Walker.
