Emily Seebohm fanned the flames of split rumours with her fiancé Ryan Gallagher on Friday.

The Olympian, 32, and former Married At First Sight star, 36, have been the target of break-up speculation in recent weeks after they unfollowed each other on Instagram and seemingly removed each other from their accounts.

Now, the competitive swimmer appears to have fuelled the rumours after she shared an Instagram post of herself and their son Sampson, one, which gives the tot her last name instead of Ryan’s. 

The original post, which contained heartwarming images of Emily cuddling up to her only child, were uploaded by the Australian Dolphins Swim Team which the retired athlete used to compete for. 

The caption read: ‘Adding to the long list of future stars who featured at Aussie Age Champs… Sampson Seebohm. Already a 2x Nationals commentator before his second birthday—now that’s poolside talent.’

It is unclear if giving Sampson his famous mother’s last name instead of his father’s was a mere slip-up, but Emily appeared to have no issue with it as she happily re-shared the images to her own Instagram page.

It came just a few days after Ryan enjoyed some quality father-son time with his son without Emily in sight, sharing a sweet photo of his toddler to social media on Thursday.

In the image, Ryan was seen beaming as he cradled the young tot during an outing in a leafy park.

He captioned the photo with some precious words: ‘Dad’s little best mate.’

The post came amid growing rumours Ryan and Emily have gone their separate ways.

The couple, who announced their engagement in early 2023 after meeting while filming The Challenge Australia, have recently unfollowed each other on Instagram.

Ryan, who starred in the 2018 season of Married At First Sight, has also seemingly removed Emily from his feed.

Emily’s last appearance on Ryan’s grid, at the time of publishing, was more than two years ago.

The post was a screenshot of the pair’s appearance on The Challenge Australia.

Even more telling, Ryan had also apparently removed a snapshot showing he and Emily with their son Sampson.

The photo captured the couple nestled together on a hospital bed, with their peacefully slumbering baby cradled in his father’s embrace.

Meanwhile, Ryan’s most recent appearance on Emily’s feed came over the Christmas season when she shared a photo which showed her, Ryan and Sampson happily posing with Santa Claus.

The Olympic swimmer also sparked rumours of a split in her most recent Instagram photo.

The image showed Emily and Sampson enjoying a mum-and-son day out at Gold Coast theme park Dreamworld.

However, eagle-eyed followers were quick to point out Emily was not wearing her engagement ring in the photo.

‘Where’s Ryan?’ one follower asked to which another replied: ‘That’s true. I hope they are okay.’

Emily also shared a clip from last month which showed her happily playing with Sampson.

Her ring was also absent in this clip, further fuelling rumours of a split between the couple.

Daily Mail Australia has reached out to Ryan and Emily for comment.

They became engaged in December 2022, a mere four months after their initial meeting while filming The Challenge Australia, and went public in March 2023.

Ryan rose to fame on season five of MAFS when he was paired with controversial series ‘villain’ Davina Rankin.

Davina was portrayed in the series as having an affair with Dean Wells, who was paired with Tracey Jewell.

She bore the brunt of ire from MAFS viewers while Ryan engendered sympathy, becoming an instant fan favourite.

Emily, who made her Olympic debut at the age of 16 at the 2008 Beijing Olympics, failed to qualify for Paris in the 100m and 200m backstroke.
