The 'Firework' hitmaker was expected to drop her fifth studio album by the end of the year but the record could now be pushed back after she started penning songs about Donald Trump's victory over Hillary Clinton, who the raven-haired star was a big supporter of.

A music insider said: "Katy has reworked the direction of her album so it reflects what she believes to be unsettling and changing times.

"She had the album ready to release by the end of the year but ... has been inspired to write new songs which she wants to add to it."

Katy - who hasn't released an album since 2013's 'Prism' - is now hoping her new tunes can help to bring "peace and unity" to the US after a number of people started protesting following the Republican's victory.

The insider added to The Sun newspaper: "As such a vocal Hillary Clinton supporter, she was heavily involved with the presidential election but was shocked at how volatile it became.

"She hopes her new music can inspire healing, peace and unity after Trump's win."

Following the US election result last week, Katy, 32, revealed her parents had voted for Trump.

She said: "What a great country this is that gives us the freedom to express our differences, our opinions, our hopes and our fears.

"Tonight, my parents voted for Trump. But you know what? We will still all be sitting at the same table for Thanksgiving."

This comes after Katy appeared to confirm she will be going on tour next year by responding to a Twitter troll who hit out at her career and standalone track 'Rise', claiming it was a "flop".

She responded: "See you at my show 2K17."
