Married at First Sight's Nicole Heir once went on a date with Gable Tostee.

When Nicole Heir appeared on the latest season of Married at First Sight, she didn’t end up with the fairytale she had imagined.

Paired with ex-Navy serviceman Craig Keller, Nicole at first seemed to be the luckiest ‘bride’ on the show. But it wasn’t long before the cracks started to appear, with a dinner party date with the other contestants ending in an angry outburst from Keller, humiliating Nicole.

It seems, however, that the Married at First Sight dinner party probably wasn’t the worst date 29-year-old Nicole has ever been on. After all, she shared on Friday that she’s been on a date with Gable Tostee.

In an Instagram post to her 29,000 followers on Friday, the Gold Coast teacher decided to start a conversation about “worst first date experiences.”

“I love getting dressed up and putting myself in awkward situations with complete strangers,” she wrote. “And having the same boring conversations only to find out he doesn’t really want anything from me but sex, he vaguely resembles his profile pics and surprise he has 3 kids or his name is Gable Tostee!”

Understandably, her fans were initially far more interested in the Gable Tostee detail than sharing their own dating stories.

In October last year, 30-year-old Tostee was accused and later acquitted of the murder and manslaughter of his 26-year-old Tinder date, Warriena Wright, and received a great deal of backlash when he appeared on 60 Minutes to tell his story in November.

In December, his most recent partner, New Zealand woman Lizzi Evans, announced their “emotionally starved” relationship was over.

The 2014 incident left many in the Australian public feeling that although he may not have been legally guilty, he was guilty of being a “horrible human being.”

Describing his puzzling reaction after his date fell to her death from his Gold Coast balcony, Tostee told 60 Minutes, “Instinctively, I knew that if I ran out there and somebody saw me looking over the edge and she had actually fallen all the way, it would look like, you know, I – it would not look good.”

Tostee had forced Wright onto the balcony and closed the door, after their drunken arguments turned into a scuffle, and proceeded to record the entire encounter.

Wright could be heard repeating the word ‘no’ a total of 33 times, and asking if she could please go home. On 60 Minutes, the recording was played back to Tostee, and he listened as his own words, “You’re lucky I haven’t chucked you off my balcony, you God damn psycho little b****,” came through the audio.

“I didn’t intend it as a threat,” he said at the time. “I intended it as a figure of speech that she was lucky I was tolerant.”

Indeed, the interest around Heir’s date with him is unsurprising. She told Sydney Confidential that she met Tostee many years ago, prior to the Warriena Wright case.

Despite the shock of Heir’s reference to Gable Tostee, many of her followers did share their worst first date experiences. They do, however, seem slightly insensitive to print here, alongside details of Warriena Wright’s tragic death.
