In another photo, she embraced her new fiancé as he smiled for the camera.

Little is known about Jae, who is one of the 732 people Kayla follows on Instagram, but his social media activity suggests he enjoys travelling and motorcycles.

The pair went public with their relationship more than a year after Kayla confirmed her split from ex-fiancé Tobi Pearce in August 2020.

The former couple, who dated for eight years and are parents to daughter Arna, co-founded Bikini Body Guides - later renamed Sweat - after meeting in late 2012.

The business partners sold their health and fitness empire to U.S. software giant iFIT for $400million last year. Tobi has since departed the company.

In May, Jae hinted he wanted to have children with Kayla during an Instagram Q&A.

He answered the question 'would you like biological children of your own one day?' with a photo of himself playing with his stepdaughter Arna and writing 'absolutely'.
