Rita Ora and Guy Sebastian dropped out for The Voice Australia

Filming for The Voice Australia is in full swing and Rita Ora and Guy Sebastian are both undergoing major transformations ahead of the new series.

Both judges have slimmed down, with Rita, 32, looking remarkably well-groomed as she landed in Sydney to film the new series.

The British singer showed off her gym-honed physique in a gorgeous gold dress that she wore off-shoulder to show off her incredibly toned upper body.

She kept her caramel locks in loose curls and ohOpted for a glamorous look with a dark smoky eye and a nude lip.

Rita let the dress be the star of the show, keeping her accessories to a minimum with just a few gold rings on her fingers.

The RIP hitmaker trimmed prior to her wedding to Taika Waititi last year and went through a grueling workout routine with personal trainer Jono Castano.

She’s previously discussed how she stays fit with Pilates, yoga, and walking, and avoids bread and sugar, focusing instead on clean meats and veggies.

Meanwhile, Guy, 41, also looked better than ever.

The singer is no stranger to competitive shows having won the first Australian Idol in 2003.

Looking excited to start filming, Guy opted for a signature colorful shirt.

He paired the red, orange and blue top with navy and blue slacks.

Guy has previously said that record labels thought he was “too fat” when he tried to break into the industry.

On the 2017 show, he revealed, “I dropped out of college and… I was recording demos and going to labels and they were telling me I was too fat.”

“They told me I didn’t look good. I was a weird looking guy with an afro, if fair enough!’ he added.

Guy has lost a lot of weight since winning the first season of Australian Idol in 2003.

In 2017, he famously unveiled an amazing body transformation after overhauling his diet and exercise regimen.

Showing off his six pack on the cover of Men’s health Australiathe singer revealed why he had struggled to lose weight in the past.

“I was in an unhealthy cycle,” Guy confessed to the publication.

‘I drank too much. I didn’t eat well. And everything that I thought I was doing right didn’t work,” he admitted.

The singing sensation went on a ketogenic diet to achieve his weight loss goals, while opting to completely cut alcohol and dairy products from his diet.

Rita and Guy were also joined by the season’s new judge, American singer Jason Derulo.

He has taken over from Keith Urban and will instead be seen in the red chair on screen with Rita, Guy and Jessica Mauboy in the new series.

The Savage Love singer was photographed sporting a funky new hairstyle. He’s let his black locks die blue and green and it looks like he’ll debut it on TV during the blind audition round.

The singer kept the rest of his outfit pretty low key to show off his hair as he donned black pants, a black t-shirt and a denim jacket.

Jessica turned heads on set as she definitely made an impression in her multicolored form-fitting midi dress.

The Saturday Night singer wore her long brown locks down with a slight wave in them.

As an accessory, she wore a silver necklace and opted for a glamorous make-up look with heavy lashes.
