The former Fleet Foxes drummer, real name J. Tillman, is shown apparently taking acid in the dreamy video for the U.S. singer's new song, Freak.

He has now revealed he channelled a real-life drug trip for his performance in the clip, remembering a time when he enjoyed a psychedelic evening at a Swift show.

According to, at a screening of the promo in Los Angeles on Tuesday (09Feb16), Misty told Del Rey of his inspiration, saying, "I took acid at Taylor Swift. I thought this was the best time to tell you."

Del Rey replied, "I forgot he did go to that show. In Australia? Good time to hallucinate?"
