Tennis champ Lleyton Hewitt and his wife Bec’s 15-year-old daughter Mia has landed a highly sought-after retail job at fashion boutique Christian Dior.

And on Tuesday, the stylish teenager was spotted arriving for her second day of work in Sydney.  

Proud mother Bec, 37, walked her daughter to the doors and gave her a last-minute pep talk and kiss on the cheek before her shift.  

One for the road: Proud mother Bec Hewitt, 37, gave her daughter Mia, 15, a kiss on the cheek in Sydney on Tuesday as the teenager headed to work for her second day at Christian Dior 

Joined by her former Home And Away star mother and 10-year-old sister Ava, Mia was dressed appropriately for her glamorous new role.

Looking every inch the high-end sales assistant, Mia wore an all-black ensemble with culotte trousers and Dior leather belt. 

She placed her brunette locks into a low ponytail with a retro grey scrunchie and accessorised with gold jewellery. 

Bec has been dressing Mia in designer clothing for years, and even went to a Christian Dior show on a mother-daughter trip to Paris Fashion Week in 2019.

The family’s flare for fashion also seems to have rubbed off on Bec’s youngest daughter Ava, 10.       

The tween had a very expensive Fendi belt bag across her chest, which is believed to be worth more than $1,200.

Meanwhile, Bec opted for a simple white T-shirt and high-waisted trousers look, with her long brunette locks worn down.   

The ladies were greeted at the door by a suited salesman, who was seen sharing a friendly conversation with Bec before ushering Mia inside.

Bec, who played Hayley Smith on Home and Away, married Lleyton in 2005 after a whirlwind romance and subsequently retired from acting.

The couple also share a 12-year-old son, Cruz, who is following in his father’s footsteps as a tennis player. 

‘Mia’s five-year plan is to move to either New York or Paris and make a name for herself,’ a source told Woman’s Day magazine last week.  

Mia was reportedly once interested in following in her mother’s footsteps by starring in Home and Away, but now has her sights firmly set on modelling.

Thanks to her famous parents, Mia likely has an advantage over many other aspiring models hoping to crack the cut-throat fashion industry.
