Katy Perry looks slimmer than ever as she steps out wearing a $1,300 Australian designer outfit in Melbourne ahead of her AFL Grand Final performance

Katy Perry hit the sights of Melbourne in preparation for her appearance in the AFL Grand Final.

The 39-year-old Teenage Dream hitmaker will perform at the Brisbane Lions vs Sydney Swans match at the MCG this weekend.

But the singer took some time off from rehearsals to go out for a night out and surprised herself with her gorgeous slimmed-down look when she returned to her hotel on Wednesday evening.

Katy, who recently showed off her much more athletic frame to celebrate the launch of her new album 143, glowed from head to toe in electric blue.

The $1,300 outfit, which featured a long-sleeved top and matching skirt by Australian designer Christopher Esber, showed off her toned abs.

The stunning design also accentuated her curves as she stepped out of her car and walked into the hotel lobby.

The Roar hitmaker wore a silver torq, silver earrings and silver rings.

She wore her dark hair loose in front of her face, in an elegant bun, with curls falling down her back.

She opted for a bright makeup look, with neutral pink lipstick and thick mascara that made her blue eyes pop.

Katy completed her look with a pair of strappy pumps as she stepped inside.

Earlier this year, insiders revealed the secret behind the Firework hitmaker’s stunning new look: his fiancée Orlando Bloom.

Despite rumors that her noticeably slimmer appearance is due to her Ozempic use, Katy has taken a cue from Orlando.

An insider claimed that Katy took over the 47-year-old’s diet and workout routines In preparation for the release of her first album in four years, she cut out processed foods and limited her alcohol consumption.

“She loves savoury food, she loves chicken nuggets and sweet food, but lately she’s been a lot more disciplined and has chosen to follow Orlando’s diet,” an insider told DailyMail.com in June.

‘She’s been working out more because she wants to perform to promote her new album. Now is the time to look good.

“Orlando has been her right hand and has helped her. They eat the same food and exercise the same. She has cut out a lot of processed food and doesn’t drink as much.

“She looks fantastic because she is sticking to the new routine.”
