The 29-year-old MAFS star had been teasing a new relationship for a while before going Instagram official with her new man in April.
"I guess this is a hard launch," she wrote alongside a picture of the couple.
Although Ella herself has not revealed any more details about her partner at this stage, both Daily Mail Australia and So Dramatic have reported that her boyfriend's name is Guy Palermo.
"Her boyfriend is very lowkey, no one knows who he is. They've known each other for six years and he's been pursuing her in that time. Love was right in front of them the whole time," a source told Daily Mail Australia.
In 2022 Ella was in a relationship with Made in Chelsea star Miles Nazaire. The pair chatted online for months before meeting in real life - with their relationship playing out on the E4 show.
However, the pair confirmed they had split in October.
"Made in Chelsea was pretty crazy. The show was intense. It was probably harder than MAFS. It's such a short period of time. I didn't find love," she explained during Channel Nine's Upfronts presentation in Sydney.
Ella Ding first appeared on Aussie screens during the 2021 season of Married at First Sight, where she was married to Mitchell Eynaud.
Despite their relationship not lasting past the filming of the show, Ella has been open about how grateful she was for the experiences, especially since it was where she met her best friend, current I'm A Celeb contestant Domenica Calarco.
“Crazy to think, if we didn’t go on MAFS we wouldn’t be travelling the world together,” Ella wrote on Instagram last year during the pair's holiday.
Since their season of MAFS wrapped, the pair are often spotted together and have even launched a podcast together called Sit With Us.
