Katy Perry has addressed claims she stole her daughter's name from a notable Australian celebrity.

The American pop star, 39, is currently Down Under ahead of her hotly-anticipated AFL Grand Final performance at the MCG on Saturday.

She spoke to radio hosts Brendan Fevola and Nick Cody about the gig and they also quizzed her on claims she took her daughter Daisy's name from their friend.

They recalled how Katy met their co-host Fifi Box and her then-baby daughter Daisy Belle, now five, when she last appeared on their show, The Fox's Fifi, Fev & Nick.

The duo asked Katy if meeting Fifi's daughter inspired her own child's name - Daisy Dove Bloom - as they recalled how much she had 'loved the name' at the time.

The Roar hitmaker shared her surprise but confessed that it might have 'subliminally' been why she decided to call her own daughter Daisy, four, around a year later.

'Is that where it came from subliminally?' Katy said while speaking to Brendan and Nick on their radio show on Thursday.

'I also love Disney and Daisy Duck, so it might be a combination of the Daisy from Australia and Daisy Duck.'

Katy, who shares Daisy with actor Orlando Bloom, also revealed she also had another unique name picked out for her daughter, but ultimately decided against it.

'I had another name for her Jupiter, but that's not the right name for her, she's definitely not a Jupiter,' she shared.

'She's a Daisy through and through, and having the last name Bloom is beautiful.'

The Dark Horse singer is set to take to the stage in front of a crowd of 100,000 AFL fans on Saturday when the Sydney Swans face off against the Brisbane Lions.

She is reportedly being paid a staggering $5million for her short pre-game performance, which will see her perform just five songs.

It was claimed that Katy and the AFL have butted heads over her setlist, with her team said to have pushed back against a request she refrain from playing new songs.

Appearing on SEN Breakfast on Monday, veteran AFL journalist Tom Morris claimed they have reached a compromise with Katy agreeing to just one new track.

'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.

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

Co-host and AFL great Kane Cornes, revealing he is 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."

'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.'''

On Wednesday, Daily Mail Australia exclusively revealed that Tina Arena will also be showcasing her vocal talents at Saturday's sporting spectacular.

The Aussie megastar, 56, has been booked in as a special guest alongside Katy and Cody Simpson, who will be singing the national anthem.

Organisers are hoping she will create another memorable TV moment after Delta Goodrum performed with Robbie Williams in an iconic show at last year's final.

It is not known whether Tina - who sings in English, Italian, French and Spanish - will be taking to the stage for the pre-game, halftime or post-match entertainment. 

Tina, known for her hit Burn and cover of Don't Cry for Me Argentina, has been signed up after plans reportedly fell through to have Kylie Minogue perform.

Katy remained coy about Tina's involvement during an interview on The Fox's Fifi, Fev & Nick, cheekily saying: 'You'll just have to wait and see.'

However, she then teased: 'All I know is that it's a fellow Scorpio… and she's great.'
