In the happy snap shared this morning, the fitness queen could be seen cosying up to her new man, Jae Woodroffe.

"Meet Jae, everyone! ❤️," the 30-year-old captioned the photo. "My best friend for years and now, partner. For all those people replying to my stories saying 'you look really happy' … thank you!! I am 😁💛."

Woodroffe shared a similar photo on his Instagram, with the simple caption, "Hi ❤️." 

In his Instagram Stories, he also shared a video of the pair walking in the park as they counted down to their upcoming holiday in seven days.

"USA with you," he captioned a timer he placed on the video.

Itsines — a trainer-turned-entrepreneur who runs the highly popular fitness app Sweat— first hinted at the romance eight months ago.

"It's early days, so I won't share too much," she told Women's Health Australia in May 2021. Although she did not reveal the person's identity, Itsines said she was "super happy".

The mogul added her new partner was the right fit as they had similar values and interests.

"We have a strong sense of family and a love for fitness [in common]," she added. 

By the end of last year, Itsines and Woodroofe were seen out and about in her native Adelaide, but it wasn't until today that she featured him on her Instagram page. 

Prior to this relationship, Itsines dated Tobi Pearce for eight years. The pair announced their split in August 2020, just one year after they welcomed their first child together: a daughter named Arna Leia. 

The couple had co-founded and launched their highly successful Bikini Body Training Company in 2014, which is now a multimillion-dollar business consisting of best-selling books, fitness accessories and, of course, the popular fitness app Sweat. 

Itsines and Woodroffe's relationship debut comes days after her ex Pearce went public with his own romance with trainer and model Rachel Dillon.

"Happiness," he captioned a series of photos of them. "I'm glad I stumbled upon you @racheljdillon ."
