I thought Miley Cyrus was a knucklehead: Bill Murray

Hollywood star Bill Murray has admitted he used to think Miley Cyrus was a "knucklehead".

The 64-year-old actor, who stars in the new comedy movie "Rock the Kasbah" alongside Bruce Willis and Kate Hudson, said he has grown to admire the "Wrecking Ball" singer, who he described as a "pro", reported Female First.

"I'm gonna say this officially, Miley Cyrus is good. I thought she was a knucklehead, funny girl. But she can really sing and she floored everybody."

The "Ghostbusters" stars said he does not want any more "bad rap" for the singer.

"I don't want to hear any more bad rap for Miley Cyrus. She's a pro," the actor said.
