Pink returned to the pop world in August with her single, What About Us, which she says was inspired in part by the state of current world politics.
She released her sixth album, The Truth About Love in 2012, when Barack Obama was the US president.
Her seventh, Beautiful Trauma, is released in October among political unrest in America and across the world.
But as an artist who has recorded anthems for underdogs throughout her career with hits such as Don't Let Me Get Me, Raise Your Glass and So What, she says she is still fighting "an old fight."
