Australian fitness queen Kayla Itsines has announced she is engaged to her long-term boyfriend, Tobi Pearce.

The 26-year-old Adelaide-based personal trainer and entrepreneur, who has nearly 10 million followers on Instagram, uploaded a picture of her stunning sparkler to social media this morning.

"It was during a family dinner which included some close friends, and I really wasn't expecting it so my reaction was of total shock and happiness. It was really romantic as Tobi was on one knee," Itsines said in a press release.

Pearce said he managed to keep the engagement plans a secret despite the two living and working together.

"Kayla is really close with her family so it was important for us to have them there. It really made it a magical moment for both of us," he said.

I’m often asked if I could change anything about my body, what would it be? I see most women saying “bigger boobs, bigger bum, smaller this smaller that”. People are very surprised when I say “I don’t want to change anything”. I know there’s a lot about my body that OTHERS would like to change, but not me. Trends come and go and what matters most to me is not likes on Instagram, sexualising myself, selling myself out, or trying to be controversial to gain followers... what matters MOST to me is that I’m healthy, I’m happy and I’m confident in myself! I honestly wouldn’t change a thing! www.kaylaitsines.com/app

Itsines is famous for being the creator of multiple successful fitness ebooks titled Bikini Body Guides.

The power couple have also formed the hugely popular 'Sweat with Kayla' app over the last four years, which helped launch their fitness business into a multimillion-dollar global empire.

Sweat became one of the top-rating and highest-grossing fitness apps worldwide.

The couple are estimated to be worth a whopping $46 million last year, according to BRW's Young Rich List.
