Miley Cyrus is high as a mother fucker.
Her words, not ours.
Cyrus is ignoring the rumors she's back together and moving in with ex-fiancé Liam Hemsworth (she was spotted wearing her old engagement ring and paparazzi caught her with a U-Haul outside his place) by uploading several clips of her singing about her favorite subject to the gram... Drugs!
She sings, "Cause you like to get high / Wanna get high with me / Drugs."
She's just being Miley.
To get a real sense for Miley's love of the tree, take a listen to her recent collaboration record with Wayne Coyne, Miley Cyrus And Her Dead Petz.
