The New Yorker, who has reportedly married 71-year-old businessman Geoffrey Edelsten in Melbourne, told the publication that the couple had legally wed.

"We just wanted to be married legally," Grecko said.

However, it seems the DJ and model was not too happy with the way the Daily Mail reported her big news.

Grecko, 25, took to Instagram to explain how the publication had caused her "very much grief".

"The entire year I have been in Australia this website has caused me very much grief," Grecko wrote alongside a picture of a badge that read "hated by the Daily Mail".

"I have been loyal about commenting back to them if they want information. This site, every single comment is degrading and cyberbullying at it's worst. Not all of them are bad but they've been humiliating on a day that is special to me. And one person will be listed on the worst journalist list. I thank the team of daily mail employees that have not tried to make me look horrible.[sic]"

 

Grecko's grief could potentially have been caused by the online publication drawing attention to two somewhat deceptive Instagram pictures she shared with her 12,000 followers before confirming her big news.

She posted two pictures of a wedding on her Instagram account but, when pressed by the Daily Mail about their authenticity, the Daily Mail said she claimed they were taken by "a friend" before removing the pictures from her account.

One of the images was a photograph taken of Danielle Spencer's marriage to Russell Crowe in 2003. While the identity of the bride in the other picture is unclear, although, based on Grecko's reaction, it seems unlikely that it is her.

Grecko had previously foreshadowed her wedding in a couple's selfie she posted on her Instagram account just hours earlier.

"Lazy day watching my mystic river [sic] with my soon to be husband," Grecko captioned the image, adding, "cool day in Melbourne".

 

The Australian bureau of the Daily Mail has provided dedicated coverage of Grecko and Edelsten's romance, often through interview exclusives with Grecko.

Last week Grecko spoke to the publication about the finalisation of her fiance's divorce from ex-wife Brynne Edelsten, saying the court proceedings would allow her to have a low-key wedding in Australia "super soon".

"I will have a new identity, Gabi Grecko Edelsten," she told the Daily Mail. "I'm really excited."

Geoffrey Edelsten, who founded the Allied Medical Group, split from his ex-wife Brynne in January 2014.

The entrepreneur met Grecko in New York City shortly after, and the couple confirmed that they intended to marry in July 2014.

Grecko debuted her engagement ring, a $45,000 diamond number, at last year's Melbourne Cup.

It hasn't been all smooth sailing for Grecko and Edelsten.

Grecko was briefly hospitalised for "stress" in July 2014, amid rumours that she had caught Edelsten text messaging other women.

However, Edelsten denied that this was the case, telling News Corp the rumours were "absolute nonsense".

"I'm loyal to her, I'm happy and very satisfied. She's a gorgeous young woman and we're very happy," he said.

In January 2015, the couple called their engagement off.

"We're trying to work it out. I am currently not wearing my ring," Grecko told Fairfax Media at the time.

She hinted that Edelsten's financial troubles - he was declared bankrupt in the US last year - were behind the couple's problems.

"I was in this for keeps but there has been so much weight on my shoulders that I don't think he or anyone else understands that the difficulties he's facing right now, I'm facing them with him."
