Another famous face is checking into American Horror Story: Hotel!

Madchen Amick will guest-star on Ryan Murphy's horror drama, reported Thursday.

The actress, who has appeared on Twin Peaks, Californication, Damages, Witches of East End, and CSI: NY, tweeted a hint about her upcoming project.

"Clue #2 of my #mysteryfilming ...this secret envelope came for me today, anyone recognize the font?" she tweeted Thursday. (Even more mysteriously, there was no Clue #1 anywhere in her timeline.)

Darren Criss is checking into AHS: Hotel... but will he check out?

Obviously, the American Horror Story font is a dead giveaway. TVLine said Ryan Murphy confirmed the news to them, and said she was playing the mother of a sick child. Chloe Sevigny will play the doctor treating him.

Amick is joining a number of other familiar first-time faces to the show, including Lady Gaga, Naomi Campbell, and Darren Criss.
