But hold those angry tweets, Directioners, because even though Haylor has reportedly called it quits, the teaser Twitpic is not what you think.
First off, as you can undoubtedly tell, it's not the flesh-and-blood Harry Miley bedded but a life-size cardboard cutout.
Turns out, Miley's little sister Noah Cyrus is an avid One Direction fan and from the looks of her big sister's latest tweets, the 13-year-old actress nabbed some series 1D swag in celebration of her birthday today.
"Wow @noahcyrus "my room is one dir-iffic," mocked Miles while posting a pic of her sister's mega-fan poster.
"This might be the creepiest thing I've ever seen," read the next tweet, along with a photo of a small Styles figurine.
Next up, the engaged Miley posted a hilarious pic in bed with the birthday girl and the facsimilie of the 18-year-old boybander.
"All I want for my birrffffday is a big booty hoe. All @noahcyrus wants for her BIRFFFDAY is @harry_styles," Miley posted along with a silly shot of the famous sisters giving the fake Styles a smooch.
And of course, Miley's pièce de résistance: a solo pic of her pretending to sleep peacefully by the British pop star's side.
