Miley Cyrus Says Her Kneecap Started to ‘Disintegrate’ Due to Infection

Miley Cyrus‘ recent infection was like a wrecking ball to her knee … ’cause she caught something that started to “disintegrate” the area — after rolling around the Hollywood Walk of Fame.

The singer-songwriter appeared on “Jimmy Kimmel Live!” Thursday night to talk about her upcoming album and accompanying film “Something Beautiful” … and, Jimmy joked Miley’s lucky she wasn’t stabbed by a loose needle while rolling around on Hollywood Boulevard.

Cyrus says she didn’t end up with a needle to the eye … but, a few weeks after the shoot, she ended up in the ICU — mainly because of a space issue instead of the serious nature of the infection.

Miley claims the doctor was shocked at the seriousness of the infection … and, he asked her if she had any idea how she could end up with such a bad contamination.

MC says she came clean about her dirty act … and, her doctor responded in the most relatable fashion — watch the clip to the end to hear what he said.

We don’t know for certain which song landed Miley on the street … though she does have a track titled “Walk of Fame” — so, if we had to make an educated guess, that’s not a bad one.

The “Something Beautiful” album comes out May 30, with the accompanying film set for premiere on June 6.
