Growing up fast! Eighteen-year-old daughter of Aussie legends attends a Pilates class in Sydney’s Bondi

Lleyton and Bec Hewitt’s daughter Mia looked the spitting image of her famous parents on Wednesday as she stepped out for a stroll in Bondi, Sydney.

The 18-year-old kept things sporty and casual as she slipped on a blue sports bra from EXIE with matching workout shorts.

She covered up against the chill with a pair of loose sweatpants and was spotted attending a Pilates class before going out to lunch.

Mia accessorised with a few silver bracelets, a beaded necklace and tucked a pair of sunglasses into her long tresses.

She let her mousy brown locks tumble down her back and opted for a completely makeup-free look.

Mia was last spotted out in January when she debuted her new boyfriend during a sunny day out at North Bondi.

The pair popped into a chemist to grab some sunscreen before they hit the beach’s famous grassy knoll, a favoured spot for influencers and locals alike.

Mia’s outing follows reports her parents Lleyton and Bec are planning on turning their tabloid fame into TV gold. 

The glamour couple was supposedly inspired by David and Victoria Beckham‘s Netflix docu-series, and hope to replicate its success with their own tell-all TV show. 

‘Bec is very organised and has awesome home videos, and I know in the past they’ve thought of doing something like this,’ a friend of the couple told New Idea.

‘They’ve watched Netflix‘s David Beckham series and loved it, and I’m sure it got them thinking.’

Grand slam champion Lleyton married Home And Away star Bec 18 years ago at the Sydney Opera House following a whirlwind romance.

The couple first met on the tennis court for a charity game at the Starlight Cup back in 1999, but didn’t reconnect until a few years later via text.

They finally decided to meet up in person in 2005, and became engaged after a whirlwind romance that lasted six weeks.

They share three children, daughters Mia, Ava, 12, and son Cruz, 14.
