The daughter of one of Australia’s most iconic couples is officially all grown up – and according to reports, she’s got a boyfriend.

The daughter of one of Australia’s most iconic couples is officially all grown up.

Mia Hewitt, the daughter of tennis legend Lleyton and actress Bec, was spotted at Bondi enjoying a day out with her rumoured boyfriend.

The 18-year-old was snapped visiting a chemist with the unknown man to buy sunscreen before taking a seat on the grassy knoll, an area frequented by locals on sunny days.

While reports claim Mia “debuted” her new man during the outing, this hasn’t been confirmed by either party.

However photos show Mia, the eldest of the three Hewitt kids, placing her arm around her companion at several moments during the outing.

Mia opted for a pair of black bike shorts and a navy blue crop during the beachside jaunt, both from activewear brand Exie.

The Australian brand was created by Project Runway winner Christina Exie, who took out the top prize in the reality show back in 2012, with the fashion designer later launching the athleisure-wear company in 2020.

“I studied Fashion Design at RMIT and graduated from the four-year honours degree in 2011, from there I went on to win Project Runway Australia, launched my namesake brand after that, then worked in the industry for about seven years to gain more skills and learn more about how to run a fashion business,” she told Greek-Australian News outlet Neos Kosmos in July 2022.

But after living in Germany for a few years, she returned to Australia, and realised she couldn’t find affordable yet sustainable activewear that made her feel “confident”.

“The activewear that existed was either over-designed or too basic for what I was looking for and their ethos was not capturing my attention. Essentially, I saw a gap in the market,” she said.

“It made sense for me to merge my two greatest loves; fashion and sport together to create an activewear brand. So, I decided to create my own designs to make me feel strong and sexy, that are manufactured in a way to be kinder to our planet.”

It seems Mia is a fan, rocking the brand’s “Flex 2.0 shorts”, which retail for $69.99, alongside the $55.99 “Uplift” sports bra in royal blue.

She paired the Exie outfit with a pair of black trainers and matching sport socks as well as a series of stacked choker-style necklaces.

Mia’s sighting comes after her parents moved back to Sydney after living in Melbourne for the best part of a decade.

Bec and Lleyton reportedly splashed out on a $10 million resort-style mega mansion in the Hills District during the relocation.

The new property reportedly comes with a host of features, including an in-ground swimming pool, tennis court, guest cottage and office.

The pair sold their previous mega mansion in Melbourne’s swanky suburb of Toorak in 2021.
