Isaac Heeney’s ex Steffie Waters shows off her tiny frame in Texas as she continues her post-split US trip after devastating breakup with the Sydney Swans star

Isaac Heeney’s estranged fiancée Steffie Waters is making the most of life on the other side of the world following her split with the Sydney Swans star. 

Waters, who flew to the States in the wake of the AFL hotel scandal, has been documenting her girls trip away in recent weeks.

On Tuesday, the blonde uploaded a new gallery of travel snaps as she bid farewell to Texas and Indiana before arriving in New York City.

‘Texas and Indiana did not disappoint,’ she captioned the post, which featured a series of photos alongside her friend Miranda Rack.

Showing off her very slim frame, Steffie and Miranda embraced the American cowboy aesthetic as they posed in tiny denim shorts and knee-high brown boots for one photo. 

She also shared photos of herself exploring local bars and watching a bull-riding competition.

The duo then headed to Bloomington, Indiana, to watch a college football game. 

Dressed head-to-toe in Indiana University merchandise, Steffie posed in the stands of the school’s football stadium with her arm wrapped around Rack. 

Steffie’s American adventure then took another turn, with the pair travelling to Manhattan’s trendy Soho neighbourhood.

Just hours after sharing her latest holiday gallery, Steffie posted an image of New York’s towering skyscrapers.

Earlier this month, she shared photos of herself and Rack attending the Austin City Limits Music Festival in Zilker Park, Austin.

The pair wore matching white crop tops and denim shorts as they danced in the crowd while watching rock band Rüfüs Du Sol. 

Steffie has also posted about shopping for vintage clothes and visiting a boutique boot store during her time abroad. 

In another photo, she was seen kneeling in prayer at a Baptist church, captioning it: ‘When you make it to Texas but our luggage did not and we need help.’ 

Her trip comes after the Daily Mail reported she quietly called off her engagement with Heeney after he was linked to the Sydney Swans scandal.

Heeney, along with teammates Chad Warner, Nick Blakey, James Jordon and Riley Bice, was stood down by the club for attending a wild party at the Pullman East Melbourne with three strippers after the Swans’ August 16 victory over Essendon.

The three dancers later made police complaints alleging they had been sexually assaulted. No charges were laid and the women have engaged civil lawyers.

The Daily Mail does not suggest the players named are personally under investigation. Their suspensions related to breaches of the club’s code of conduct, including drinking and bringing women back to hotel rooms, and were not connected to the police investigation.

Weeks after the fateful night, Steffie is said to have been unable to forgive what she sees as Heeney’s betrayal by partying with strippers.

Within hours of the hotel scandal breaking, she fled the couple’s $4million Maroubra home and flew interstate to Noosa to avoid the media storm.

It is understood that Heeney spent weeks trying to save their relationship and kept in regular contact with her in the hope she would come around.

But after weeks of soul-searching, friends said Steffie ultimately could not move past what she considered an act of infidelity after he partied with exotic dancers.

‘She is dealing with the breakdown of her relationship that has nothing to do with the allegations [to police], only the fact that Isaac has been unfaithful [in her eyes],’ a source told the Daily Mail.

According to friends, the ongoing investigation was why Steffie had been grieving the break-up away from public view. She felt unable to make a public statement about their engagement out of respect for the official process.

‘There are a lot more people involved than just her and Isaac so she is trying to be mindful of everyone,’ added the source.

The Daily Mail makes no suggestion that Heeney acted unlawfully, only that Steffie viewed his partying with strippers as a breach of trust in their relationship.

When the news of the strippers’ accusations first broke, trolls targeted Waters with abusive comments under some of her loved-up photos with Heeney.

Friends say the public backlash was particularly difficult for her to deal with while navigating her own heartbreak.

‘She is lying low as much as she can and she has support around her. We wish she could do that in private, but she can’t,’ said a confidante.

Steffie and Heeney, who had been dating for several years, became engaged while on holiday in French Polynesia last October.

With their model looks and prominent standing within the club, the two soon became something of a Swans poster couple, regularly attending official events together.

Steffie’s social media portrayed her as a dedicated WAG who attended many games and proudly cheered on her man, the club’s blond-haired golden boy.

She often posted happy snaps alongside other Swans WAGs and even designed her own unofficial supporter outfit with Heeney’s name across it.

On September 19, in what was understood to be her first tentative step towards moving on, Steffie deleted several of their photos together, including their engagement post.

‘She could have done that in private but she can’t so all we can do is try and focus on supporting her,’ said a friend.

‘It’s sad. She was engaged to be married, planning a wedding, building their dream home. He was the love of her life.’

The split news comes amid growing belief in AFL and legal circles that sexual assault charges may be difficult to prosecute following a review of the evidence.

No charges have been laid and there is divided opinion over whether a secret recording seized by police in early September, and hailed as shedding light on the case, would be admissible in court.

The Victorian Director of Public Prosecutions is expected to receive a brief of evidence from the sexual crimes squad by the end of the month.
