Defiant Katy Perry belts out two new songs from latest album during AFL Grand Final set following reports she clashed with AFL bosses over setlist

Katy Perry belted out two new tracks during her blockbuster Grand Final performance in Melbourne on Saturday, despite reports that the AFL were not keen on her song choice.

It was reported this week that the AFL wanted the popstar, 39, to sing only one track off her new album, 143, while Katy's team wanted two in the set.

In the end Katy, who was paid a reported $5million to perform on Saturday, got her way with two tracks from her recently released album getting a run at the MCG.

Katy's 20 minute set included Lifetimes and Gorgeous, her collaboration with Kim Petras .

Despite slipping the new songs in, it was the hits that got the crowd pumping with Katy kicking of with a rendition of Roar before ripping into her hits Teenage Dreams, Dark Horse and Firework.

Katy also belted out a rendition of I Kissed A Girl with Tina Arena before the pair moved into a rendition of the Aussie pop star's hit Chains.

It was reported this week that Katy Perry and the AFL had butted heads over the songs the US pop star would sing at the Grand Final performance.

Appearing on SEN Breakfast on Monday, veteran AFL journalist said Tom Morris claimed that Katy's team had pushed back against an AFL request that the Teenage Dream hitmaker perform just one new song.

'She's playing about five songs and the AFL was very keen for her to play five classic tunes, she wanted to play two new ones,' he said.

Tom added that both camps had reached a compromise with Katy reportedly agreeing to just one new track.

'In the end they met halfway and she's playing one new song and four classics,' he said.

Co-host and AFL great Kane Cornes, admitting he was a Katy Perry fan, added that the AFL should have a say in the planning of the blockbuster stadium show .

'The AFL are saying: "We only want your hits. We only want your bangers. We only want your best stuff"' he said.

'We want Roar, We want Teenage Dream, we want Firework. They want all the songs we know and love. And she's pushed back and said, "No, no I want to play two of my new songs."

He added: 'You know when you go to a concert and maybe they're old and all you want is their good stuff. You just want their greatest hits.

'That's what the AFL have requested with Katy Perry. And she's gone: "clearly, I want to promote some of my new music.'''

Katy released her latest album 143 last week, which contains the controversial first single Woman's World and follow up Lifetimes.

The singer released the lead single from 143 in July, but the track - billed as an empowering feminist anthem - was quickly dismissed as unoriginal, hypocritical and formulai c.

The Teenage Dream hitmaker also faced criticism for the sexualised nature of the accompanying video, as well as her decision to work with music producer Dr. Luke, 50, after his highly publicised legal battle with Tick Tock singer Kesha, 37.

Reviews for 143 have not been too kind to Katy, with Variety brutally stating that the album 'strips away the remnants of the perky personality that catapulted Perry into early 2010s superstardom.
