Katy Perry thrills her Melbourne fans with an impromptu meet and greet ahead of her AFL Grand Final appearance

Katy Perry fever has officially hit Melbourne as the American pop star has landed in preparation for her performance at this weekend’s AFL Grand Final.

And the Teenage Dream hitmaker treated fans to a special event on Wednesday with an impromptu meet-up.

Katy, 39, looked stunning in a tight, ankle-length black dress by Parisian designer Coperni as she posed with fans outside the Channel Ten studios ahead of her interview for The Project.

The stretch dress featured a high turtleneck and had a futuristic look thanks to the round silver embellishments.

The gorgeous dress hugged Katy tightly, showcasing the pop star’s enviable figure.

She completed her outfit with a pair of simple black pointy heels.

Katy wore her raven black locks pulled back for the occasion and accessorised with silver earrings.

She completed her look with a light pink blush and a matching lip color.

Hundreds of fans waited patiently to take a selfie with the pop idol, and Katy was more than happy to oblige.

Katy looked completely in her element and happily posed for countless photos for her fans.

She seemed genuinely happy to be in the company of so many adoring fans and beamed from ear to ear as she approached.

While there were plenty of fans who wanted to spend some time with their pop idol, there was one in particular who caught Katy’s attention.

A superfan brought his dog along for the meet and greet and the adorable pooch was decked out in an outfit that read “I love Katy Perry”

The feeling wasn’t lost on the Roar singer, who took the time to meet her human fans and give the puppy some special attention.

She even gave the superfan a kiss before gratefully signing the dog suit.

It appears Katy Perry and the AFL are at odds over the songs the American pop star will sing at the upcoming Grand Final in Melbourne.

The hitmaker was announced as the headliner for next weekend’s match back in July.

In an interview with SEN Breakfast on Monday, a veteran AFL journalist said Tom Morris claimed Katy’s team had resisted an AFL request that the Teenage Dream hitmaker only perform one new song.

“She plays about five songs and the AFL really wanted her to play five classic songs. 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 song.

“They ended up meeting halfway and she plays one new song and four classics,” he said.

Co-host and AFL legend Kane Cornes admitted he was a Katy Perry fan and added that the AFL should have a say in the planning of the hit stadium show.

“The AFL says, ‘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 that we know and love. And she 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 they’re maybe old and you just want their good stuff. You just want their greatest hits.

“That’s what the AFL asked Katy Perry. And she’s gone: ‘Obviously, I want to promote some of my new music.'”

Katy released her latest album 143 last week, featuring the controversial lead single Woman’s World and its follow-up Lifetimes.
