Melbourne, Sept 05: Hannah Montana star Miley Cyrus’ hit single ‘7 Things’ is reportedly about what she hates in her ex-boyfriend Nick Jonas.

The video’s director, Brett Ratner, revealed that Cyrus had discussed the song with him and had even told him how much the song, which she co-wrote, means to her, and that it was about an ex-boyfriend.

Even though Ratner refused to reveal who the ex-lover, to whom these words were written "Your friends, they`re jerks. When you act like them, just know it hurts," was, he gave away a detailed clue that all but confirms the song is about Jonas.

Cyrus had herself recently admitted, after months of unconfirmed speculation, that she dated Jonas for two years.

"She had me come out to her house," the Daily Telegraph quoted Ratner as saying.

"She started showing me all of her personal items from under her bed that her ex-boyfriend gave her. So she pulled out his dirty socks and a bunch of photographs.

"The necklace she`s wearing in the video is the necklace he gave her.

"She`s wearing his diabetes or medical necklace,” he added.
