Rebecca Judd has a Baywatch moment as she shows off her incredible figure in red bikini with husband Chris on Melbourne’s Brighton beach

Rebecca Judd battled the heat on Saturday as she headed to Melbourne’s Brighton Beach with her husband Chris Judd.

The AFL WAG showed off her killer physique in a stylish, barely-there bikini as she went for a swim.

The 41-year-old had a Baywatch moment as she raised her arms in the air and showed off her ripped figure.

The skimpy swimwear from Swiss brand Bongénie Grieder featured a sassy cutout under the bust and a blue ring detail that kept the top closed.

She added high-cut bottoms with the same ring details and matched the blue with her designer Loewe bucket hat.

Bec appeared to wear minimal makeup for the outing and tucked her hair into the hat.

Later, she sat on a blanket as she scrolled through her phone in the shade.

Meanwhile, husband Chris enjoyed a dip in the water wearing red and blue striped board shorts.

The high-profile Melbourne couple also had their brood of four young children in tow.

Chris, 40, showed off his toned body as he tossed around a tennis ball with his sons, who wore identical swimmers.

Bec shares four children with her former foot champion husband, including eight-year-old twins Tom and Darcy, daughter Billie, ten, and Oscar, 12.

It comes after Bec recently sparked fears she was ‘too skinny’.

Concerns over the model’s physical appearance came after Bec posted photos of herself in a vibrant yellow outfit last week.

In the images, the stunner showed off her very slim body in a two-piece ensemble from Elyia The Label.

The conversation about her figure started on Facebook when a user commented that she looked “too skinny,” sparking a series of comments.

Another wrote: ‘For God’s sake give her a good feed.’ A third echoed comments such as ‘give her a burger’ and ‘buy a happy meal’.

However, others stepped in to defend Judd.

“She looks good, only the couch potatoes will put her down because they can’t put down the chips,” said one, suggesting the criticism was rooted in jealousy.

Bec recently revealed she plans to donate the entire contents of her mansion on Victoria’s Mornington Peninsula to charity.

She posted to her Instagram Stories to share her plans with her 758,000 followers, while asking for advice on which charity to donate to.

Rebecca explained how she and her husband are renovating their $1.2 million home and want to donate all their current furniture to charity.

She said everything in the property would be included – from crockery to appliances – and shared her wish to donate to a refugee housing charity or women’s shelter.

She wrote: ‘We are about to renovate our Mornington Peninsula home and would like to donate the entire contents to a charity that needs a full house fit-out.’
