Are the couple Jayden and Eden still together? Telling Instagram photos will determine their current relationship status

The new season of Channel Nine's ratings Married at First Sight has only just begun.

And now a former reality series star has revealed a major spoiler for fans after sharing tell-tale photos to his social media on Thursday.

It looks like Jayden Eynaud, 26, and Eden Harper, 28, who just tied the knot this week, survived the experiment and are still together.

Jayden's brother Mitch Eynaud, who appeared on the show in 2022, posted a gallery of photos of himself cuddling a large dog that looks suspiciously like Eden's golden retriever named Cub.

Fans quickly jumped to the conclusion that Mitch, 28, updated viewers on Jayden and Eden's current relationship status.

“I see what you did there,” one fan commented on Mitch's photo.

“Dead giveaway, thanks Mitch,” wrote another disappointed fan, who signed his response with a kiss.

“Spoiler alert,” another fan wrote.

Meanwhile, another viewer warned Mitch, who was paired with Ella Ding on MAFS in 2022, about a possible network backlash.

Spoiler alert! Mitch Eynaud posted to his social media this week a gallery of photos of himself posing with a dog that looked suspiciously like Eden's, hinting to fans that Eden and Jayden may have survived the experiment as a couple.

“Don't this show us Eden and Jayden staying together!” one follower said of the photos, which show the former reality star cuddling the dog in various poses on a couch.

They added: 'Channel 9 wouldn't want you posting this!'

An eagle-eyed viewer thought there was no doubt the big dog was the same one Eden paid tribute to on her social media in October after spotting a crucial clue.

The couple, who immediately hit it off on their wedding day, may have encountered something for the first time – and it all has to do with personal care.

“Jayden doesn't wash his hair,” Eden told Daily Mail Australia on Thursday.

In response to his wife's comment, Jayden quickly clarified, “Well, I was,” he replied.

“Like every fortnight, once every couple of weeks,” the athlete turned reality TV star laughed.
