Fitting right in with the crowd, Paris wore a studded leather jacket, black pants and boots. She was also still sporting the bracelets she was spotted wearing after leaving the hospital following the incident on Saturday.
The 20-year-old held onto her boyfriend, Gabriel Glenn, while posing for photographers on the carpet.
As The Blast previously reported, Paris was rushed to the hospital after she allegedly slit her wrists over the weekend.
She's not the only celebrity to show their support for the Mötley Crüe biopic. Pete Davidson, Machine Gun Kelly, Bella Thorne, Steve-O, Tony Hawk and Fred Durst were among the A-listers in the audience.
After the premiere, there was an after-party at Whisky a Go Go, where the band and their famous friends really let loose.
