As we previously reported, Miley Cyrus is inducting one of her biggest idols, ultimate badass Joan Jett, into the Rock and Roll Hall of Fame. Well, the institution's 30th Annual Ceremony (presented by Klipsch) is happening tonight (April 18), and Miley is currently sharing her excitement via Instagram.

"F-ck yo Saturday!" Miley captioned this photo of Joan. "I'm spending mine with this f-cking BAEEE!!!!"

In true Miley fashion, nothing says "moving tribute" like nipple pasties.

They stuck Miley in room 420? C'mon, wayyy too easy.

Miley is just one of many giant stars set to appear at the ceremony in Cleveland: Patti Smith, Paul McCartney, Fall Out Boy, Stevie Wonder, and more will act as presenters. In addition to Joan Jett and the Blackhearts, other inductees include the late Lou Reed, Ringo Starr, and Green Day.

Miley has been a huge fan of Joan Jett for a really long time, and it's for good reason: after first getting her start as a teenage guitar prodigy in the Runaways, Joan embarked upon an enviable solo career, releasing countless hits like "I Love Rock n' Roll" and "Bad Reputation."

Also, let's never forget that time Miley sang with Joan Jett live on Oprah. Seriously, #NeverForget.

HBO will air a broadcast of the Induction Ceremony on May 30th.
