Mia Hewitt enjoys the attention in skimpy red bikini with her rockstar boyfriend at the beach

Bec and Lleyton Hewitt's teenage daughter Mia hit the beach with her boyfriend to end the working week. 

The musician was joined by her rocker boyfriend, Vanda Erich, as they soaked up the overcast humidity at Bronte on Friday.

The 19-year-old opted for a cherry red underwire bikini, which she paired with black sunglasses to protect her eyes from the sun.

The teenager went makeup free and wore her caramel loose around her shoulders and kept her silver accessories to a minimum, sporting a hair band on one wrist and a simple bracelet on the other. 

Vanda meanwhile went shirtless and wore black Canterbury swimming trunks, accessorised with a simple string necklace that Mia affectionately adjusted as she touched his bare chest. 

While they're not 'Instagram official', the pair have been seeing each other for several months and appeared unfazed by the presence of paparazzi at the Sydney hotspot.    

The couple appeared happy and relaxed as they headed down to the water, chatting and smiling as they held up peace signs for photographers.

Mia and her boyfriend went for a quick dip before returning to the sand to laze on their beach towels. 

Mia, who celebrated her nineteenth birthday last week, looked at ease with the attention, as she tossed her hair over her shoulders while standing above Vanda as he relaxed on the sand.

Vanda, who plays in rock band Liquid Zoo, appeared to be accompanied on his beach date by at least one of his three male bandmates. 

Mia grinned at him as she clutched a towel around her figure after her swim, and later affectionately repositioned her boyfriend's necklace.  

The teenager celebrated 'another lap around the sun' with a house party last weekend. 

She rang in her nineteenth birthday with  friends, in what appears to be an Inner West share house, near to the venues where she performs with her indie band, Father's Daughter. 

In a case of life imitating art imitating life, Mia has styled her on-stage image like the enigmatic front woman of the fictional '70s band, Daisy Jones and The Six. 

The character, loosely inspired by Fleetwood Mac, was recently depicted  by Elvis Presley's granddaughter and fellow 'nepo baby', Riley Keough. 

Mia and her friend Cherise bill their band as a 'bohemian folk rock duo that captures the spirit of the 70s with a modern twist, channeling the essence of classic legends like Fleetwood Mac and Nancy Sinatra.'

In a recent photo dump shared to the band's Instagram account, the teen rockers labelled themselves 'The Queens of King Street'. 

The main road in Sydney's Newtown is the beating heart of the suburb's eclectic live music, arts, and foodie scene that's beloved by starving artists and the LGBTQ+ community.   

But starving artist, Mia is not. 

When the young performer wraps up her gigs in dingy dive bars around the Inner West, she returns home to her parents' $10.3million Glenhaven Estate. 

Her parents bought the resort-style, coastal estate with a six-bedroom residence on the quiet from former Parramatta Eels great Nathan Hindmarsh and his interior designer wife Bonnie Hindmarsh, last November. 

Mia's parents, the Hewitts, were for years the reigning king and queen of Australia’s gossip magazines.

The couple, who were married in Sydney in 2005, hired some 50 security guards to keep paparazzi and the public at bay while helicopters hovered overhead of the wedding. 

One-time pop star Bec looked every inch the proud mum as she attended one of Mia's recent performances at Oxford Art Factory.
