She posed with the icon rocking plastic pastie hearts with J's on them.
Yowza, Miley!
The singer was excited to meet and perform for rock icon Joan Jett at her Rock and Roll Hall of Fame induction Saturday night. So excited, in fact, that she decided to wear pink plastic nipple pastie hearts with J's on them to the event.
"Joan's cheerleader," she captioned the pic.

She also snapped a pic of her delightfully appropriate dressing room.
"4 f---ing 20," she wrote. Then she took a photo next to a "No Smoking" sign and captioned it "Yeah right."
Then, she got what might be the entertainment photo of the century: Herself in the nipple pasties with Joan Jett and Sir Paul McCartney.
"F--- yeah!" she captioned the pic.
On stage for her performance and Jett's induction, Miley Cyrus went a little more demure with a black top over the pasties. In an Instagram she posted Sunday morning, she is showing off another signature Miley move: The tongue sticking out.

She and Tommy James performed "Crimson and Clover" with Joan Jett and the Blackhearts as part of the ceremony.
Later, she and Joan Jett hugged it out onstage.
And backstage. "My 1 & only" she captioned this Instagram shot.
Jett wasn't the only inductee that night -- new members of the Rock and Roll Hall of Fame include Ringo Starr, Bill Withers, Green Day, and Stevie Ray Vaughn. Jett and Cyrus sat next to one another during the banquet and while the other musicians were inducted.
