“The Bachelorette” Australia 2015 star Sam Frost has been a no-show on her first week on the job.

The reason of her absence on the breakfast radio show on Thursday was not actually her new boyfriend Sasha Mielczarek, but because of a prior engagement.

On the show’s Twitter account, it stated that Sam has a prior commitment, and Rove McManus’ former “Rove Live” colleague Peter Helliar will be stepping in as co-host for the day.

According to Sydney Confidential, Frost had mentioned in the show the said prior engagement a day before.

Later on Thursday, the reality star was spotted attending a breakfast beauty launch for Alpha Keri moisturizer in Sydney, Daily Mail noted.

The night before her no-show at the 2Day FM show, Frost attended the WHO Most Intriguing People 2015 party with Sasha.

Frost told reporters at the party that she had given herself a curfew of 10 pm to be on air in the morning, Sydney Confidential reported.

The reality star was announced as Rove’s co-host on the breakfast show last month, days before “The Bachelorette” Australia 2015 finale. She started her stint on Monday.

Meanwhile, Sam and Sasha’s sexy bedroom shoot will be on WHO’s special issue of Australia’s 2015 Most Intriguing People.

In an interview with WHO, Sam admitted that she can’t still believe that she finally found the man of her life.

“This year’s been very surreal. I pinch myself every day and I think it’s a true blessing that I’ve got the love of my life and so many people supporting me. Today I feel strong and I honestly feel like I’m the luckiest person alive,” said Sam.

“I found the love of my life. I can’t believe it. It blows my mind,” she added.

When asked about their plans in the future, Frost said: “Hopefully buy a house and go on a holiday. And buy a puppy!”

“Hopefully for New Years’ we’ll be overseas celebrating together,” Sasha added.

It was previously reported that the new couple is already looking for a possible venue for their upcoming wedding on the Fijian coral coast.
