Simone Holtznagel jets off on holiday after ex-boyfriend Jono Castano unveils new girlfriend

Simone Holtznagel has treated herself to a holiday following ex-boyfriend Jono Castano debuting new girlfriend Nilofar Khirzad.

Simone, 31, took to Instagram on Thursday to share a glamorous photo from her lavish getaway to the Whitsundays.

The Australia’s Next Top Model finalist stunned in a red dress as she posed in front of a marble wall at the Intercontinental Hotel on Hayman Island in North Queensland.

The slinky outfit revealed a slither of the mother-of-one’s toned midriff and clung tightly to her eye-popping assets.

The off-the-shoulder number was decorated at the neckline and the waist with golden flower brooches. 

Simone went for a smokey eye makeup style with a light red lipstick.

In the caption to her post, she announced that she was ready to relax after an eventful few months.

‘Holiday Mode,’ the blonde beauty wrote.

Jono debuted new girlfriend, fashion designer Nilofar Khirzad, in Sydney’s eastern suburbs on Sunday. 

The generically blessed hot new It couple were dressed to impress as they took full advantage of the stunning weather.

Jono, 33, offered a hint of man cleavage in an oversized shirt in apricot that featured a wide, open neckline. 

He completed his look with shorts in the same delicate shade and a pair of white trainers. 

Elsewhere, all eyes were on Nilofar who turned heads with her very leggy display. 

The brunette bombshell turned up the heat in an ensemble that featured a lemon, long-sleeved crop top adorned with green lace, and a matching skirt that revealed her never-ending tanned trim pins.

Jono and Simone quietly split nine weeks after they welcomed their baby daughter Gia on Easter Sunday.

He confirmed news of their break-up in July, and Simone has since said she is raising Gia alone and cryptically remarked that she ‘couldn’t change’ the man she loved.

‘I wanted to set an example for my daughter; that’s something that shifted for me. One day I was like, ‘What am I doing? This isn’t right.’ And I would hate if she was ever in this situation,’ she told Stellar.

‘You have to do what is right for you at the end of the day. No matter the number of promises or anything else that people make, when they show you who they are, believe them. Because you can’t change people.’

Simone also said she is content raising her baby Gia, six months, alone and that she is confident she made the right choice.
