Katy Perry Goes ‘Old Hollywood’ At Premiere Of ‘Jeremy Scott: The People’s Designer’ [Photos]

Katy Perry was looking quite glamorous on Tuesday night at the premiere of Jeremy Scott: The People’s Designer at the TCL Chinese Theatre in Los Angeles. According to Celebuzz, the Teenage Dream singer wore a long black gown with a sexy thigh high slit by Moschino (naturally). Katy Perry’s gown went hand-in-hand with Jeremy Scott’s suit, which was done on purpose. Katy said that they were “twinning,” and they both seemed to love every minute.

Katy Perry and Jeremy Scott took part in a handprint ceremony before entering the theater. Scott tweeted about the special moment a short time after.

And, in case you were wondering why Katy was on Jeremy’s arm, the two have become very close friends over the years.

“[Perry] is one of Scott’s most notorious muses. Perry and Scott attended the Met Gala together (along with Madonna, also wearing Moschino), and Scott designed Perry’s costumes for her Super Bowl XLIX Half Time show performance. Back in June, Perry was named the face of Moschino.”

Katy Perry also stars in Jeremy Scott: The People’s Designer. According to Us Weekly, Jeremy Scott was not the least bit shy when talking about Perry, who has been a huge part of his career and his life.

“Katy is the arc of the film. When you see it, you’ll understand. There’s these iconic moments that everyone knows — like her on the field for the Super Bowl and us at the Met Gala on the stairs. And me kissing her hand. But then you have us in the car and me nervous, and her making me laugh and putting me at ease,” Scott said.
