"A Queen is never late; everyone else is simply early. #pillowchallenge," she captioned her post.
In her post, she's rocking a pair of headphones and sunglasses, an homage to the original Princess Diaries movie poster.
Anne also put her own twist on the challenge, which requires you to fashion a dress out of a pillow and a belt. Anne used three pillows (two white and one blue), and is standing in front of a cute blue butterfly wall. She also accessorized with combat boots, which are very Mia Thermopolis-esque. Anne, of course, starred as Mia Thermopolis in the iconic 2001 movie and the 2004 sequel, The Princess Diaries 2: Royal Engagement, alongside Julie Andrews as the disapproving yet loving Queen Clarisse.
Here's the original movie poster for reference:
Obviously, Anne's and followers are absolutely loving it.
Actress Jessica Chastain commented, "Hahaha I LOVE YOU! ". And another follower commented, "no one does it like Anne Hathaway or should I say Amelia Mignonette Grimaldi Thermopolis Renaldo!?!? " While another wrote, "This caption is really everything I needed right now." And one fan commented, "GIVE US THE THIRD ", in reference to hopes of a third Princess Diaries someday being released.
Here's everything we know about the third film so far:
Meanwhile, tons of other celebs have also participated in the #pillowchallenge, including Halle Barry.
Tracee Ellis Ross also put her own spin on the challenge.
And Sarah Michelle Gellar also did the it, complete with super cute pigtails.
