Last year (14), Trindl hit the siblings with a $5 million (£3.1 million) suit, claiming they dropped him from the electronic dance music group after he refused to go back to rehab.

The Yousafs insisted Trindl quit the band voluntarily, and now Forbes magazine reports that both sides have since come to a settlement.

The sisters were interviewed by the publication in July (15), mentioning they had "received paperwork to settle a lawsuit from a former bandmate after finishing their show."

While they did not go into detail on the settlement, the music stars did discuss how the lawsuit triggered a backlash of the duo's musical abilities, and they were subsequently inundated with cyberbullying and sexist criticisms.

The controversy prompted Jahan to write a piece for Billboard, addressing the online abuse in an op-ed.

She wrote, "People went immediately into believing everything that they read... People wanted to immediately jump to these conclusions that 'Of course they're women, they use their sex to sell the group. They manipulate men in the industry. They can't be trusted.' And those were the constant themes that we kept seeing."
