One of the major highlights coming from Travis Scott’s Astroworld Tour is the incredible rollercoaster experience that’s been creating crazy buzz and applause from fans since its debut.

Mötley Crüe drummer Tommy Lee obviously feels slighted because he is now accusing the “Sicko Mode” artist of lifting it from his 360-degree drum rollercoaster design, which he first broke out in 2011. He’s also accusing Travis of jacking his Crüecifly design as well.

“Just found out this fucking idiot @travisscott or someone on his team ripped off the 360 AND The Cruecifly! WTF!! Get an original idea bro …,” Lee wrote under an Instagram comparing the contraptions.

He later wrote in a separate Instagram post, “I get copying is a form of flattery, but this is just straight ripping off my shit. What do you guys think???”

Lee’s rollercoaster allowed him to perform his drum solo over audiences for approximately four years, including Mötley Crüe’s Final Tour in 2015.

Mr. Lee moved his complaints to Twitter and told Travis to “lawyer up.”

Ironically, in 2014 Tommy was taken to court over that same 360-degree design. Lee won the case however, on the basis that the drums made it the rock legend’s original concept.
