Former Australian actress Bec Hewitt is reportedly navigating a challenging chapter alongside her husband, tennis legend Lleyton Hewitt, amid significant changes within their family.

Bec, 42, and Lleyton, 44, captured the nation’s attention when they debuted their romance in the mid-2000s, quickly becoming Australia’s answer to Posh and Becks. 

Now, more than two decades into their marriage, it’s understood Bec has been riding an “emotional rollercoaster” as their three children: Mia, 20, Cruz, 17, and Ava, 15, grow older and increasingly independent.

According to sources close to the former Home & Away star, Bec has been feeling “sad” and “alone” as her children carve out lives away from home.

“For the last 20 years, she’s (Bec’s) been a full-time mum, and now with the kids off doing their own thing, and with Lleyton’s ceaseless devotion to tennis, Bec’s been left with nothing to do,” a source told New Idea.

“As the kids get older, Bec’s seeing less and less of them, which makes her sad.

She’s twiddling her thumbs trying to find something meaningful to do with all of her spare time, but she’s finding it difficult.”

The couple’s eldest daughter, Mia, is a musician and model who is dating the lead singer of Sydney-based band Liquid Zoo, Vanda Erich.

Their son Cruz is following in his father’s footsteps on the court and is currently ranked 735 on the ATP rankings.

Meanwhile, their youngest daughter, Ava, like most teens, reportedly doesn’t have “much time for her mum anymore”.

Bec previously opened up about stepping away from acting to focus on raising her family in a 2018 interview with Stellar. 

“It was never a choice- a decision- that I made [to quit acting],” Bec told the outlet. 

“It just naturally happened because, obviously, I wanted to be there with the kids. I don’t want to miss anything.”

At the time, Bec said she felt “fortunate” to be travelling with Lleyton, seeing “wonderful places” and creating memories with her children.

“I am with the kids all the time,” she shared. “Every minute of the day. And I love it.”

Lleyton recently praised his wife’s unwavering support during his induction speech at the Sport Australia Hall of Fame gala dinner. 

“It’s not easy being a partner of a tennis player,” the former world No.1 said.

“And she’s (Bec’s) done everything with grace and elegance and you’ve been the rock the whole time supporting me, and I certainly wouldn’t have been able to continue my career and be able to play 20 Australian Opens without you,” he continued.

“So I’m eternally grateful and I love you so much. Thank you.”

It’s understood Bec and Lleyton are currently in Queensland supporting Cruz as he competes in a doubles event at the Brisbane International. 

Following the Brisbane tournament, Cruz has also received a wildcard into the qualifying draw for the Australian Open, which begins on Monday in Melbourne, with the family expected to be there to cheer him on.
