rock ‘n’ roll boyfriend Vanda Erich.
The lovebirds were spotted having a fun day out at Bondi beach together before going for a bite to eat at Rose Bay House.
With her brunette locks blowing in the breeze, Mia, 18, who is the daughter of tennis ‘It Couple’ Bec and Lleyton Hewitt, opted for a $238 ʙικιɴι from Highrack Studios.
The retro two-piece featured a purple base with orange flowers, keeping it in line with Mia’s usual ’70s inspired style.
Fitting with the old school look, Mia paired her bathing suit with a pair of high waisted jean shorts, brown belt and red tinted shades.
She also donned a pair of comfortable black sandals, and at one point covered up with a billowing white shirt.
Meanwhile, her musician partner rocked up to the beach in a pair of jeans and white cropped T-shirt which read Attention Ladies I Listen To Liquid Zoo.
The rocker, who is the frontman for his band Liquid Zoo, accessorised with a set of orange tinted glᴀsses and black Adidas sneakers.
Stripping down to a pair of black swim trunks when he reached their destination, Vanda and Mia went about finding a comfortable stretch of grᴀss to stretch out on.
It comes after Mia performed her first gig with her band Father’s Favourite, a ‘bohemian folk rock duo’, over the weekend.
She looked incredibly stylish as she performed at a brewery in Sydney, rocking a mini white skirt and black top as she wowed the crowd.
