Joan Rivers has slammed Miley Cyrus recent antics as ‘disgusting’.
The legendary comedian told OK magazine: ''Enough! That girl is disgusting. She should know her audience, and her audience is 17-year-old girls!"
She added: "'I would never have let Melissa go to a concert like that at 17 years of age.
"'There has got to be authority figures and people who have checks and balances on these young kids, especially since things have become so out of control with the internet.''
Cyrus has caused controversy in recent months with a string of raunchy performances and music videos.
She also engaged in a war of words with Irish singer Sinead O’Connor.
