It’s no secret that Travis Scott’s ‘ASTROWORLD: Wish You Were Here’ Tour has taken its amusement park inspiration to the next level, even making use of a large-scale rollercoaster on stage. But there’s one star who’s taken umbrage with the rapper’s set design.

Former Motley Crüe drummer Tommy Lee took to Instagram to accuse Scott of copying two of his alleged original concepts, writing, “Just found out this fucking idiot @travisscott or someone on his team ripped off the 360 AND The Crüecifly! WTF!! Get an original idea bro….ANNNNND not one rip off but TWO. DOPE. I get copying is a form of flattery, but this is just straight ripping off my shit. What do you guys think???”

He doubled-down on Twitter, advising the rapper to “lawyer up!”

Scott has yet to respond, but this isn’t the first time that a major player has been accused of stealing stage ideas this year. Earlier this month, singer Lorde took to her Instagram Stories to share a slideshow of images comparing her recent ‘Melodrama World Tour’ set to that of Kanye West and Kid Cudi’s Kids See Ghost show at Los Angeles’ Camp Flog Gnaw festival.

At the time, she wrote, “I’m proud of the work I do and it’s flattering when other artists feel inspired by it….but don’t steal—not from women or anyone else—not in 2018 or ever.” But both the duo’s set designer (John McGuire) and Lorde’s stage designer (Es Devlin) have since rejected that allegation.

This appears to be a distinct departure from Lorde’s previous relationship with Kanye, circa 2014, when the rapper provided an official “rework” remix to her The Hunger Games: Mockingjay – Part 1 lead single “Yellow Flicker Beat,” and then said of West to Rolling Stone, “He’s so private I feel weird talking about how he does stuff. I feel lucky to even be in a room with him.”
