Lawrence's close relationship with 'Hunger Games' costar and the 'Wrecking Ball' hitmaker's former fiance, Liam Hemsworth, is also one of the factors behind the feud, Stuff.co.nz reported.
A source has revealed to British magazine Heat that Cyrus feels it is fake how the 23-year-old actress always tries to act like a feminist in all her interviews, but then poses in a revealing dress to promote her film.
The insider said that the 20-year-old singer is mad as hell and she thinks that Lawrence is a hypocrite, and she basically wears nothing but body paint in X-Men and that she was all over Hemsworth on the red carpet.
The source insisted that Hemsworth kept telling Cyrus how great Lawrence was, so that got her back up, and when the two finally met, Cyrus felt that Lawrence had all her attention just toward Hemsworth.
The insider added that Cyrus had always suspected the 'Hunger Games' actress didn't like her and that she would side with Hemsworth, and that the pics of the to costars getting close really made her furious.
