Rebecca Judd and her husband Chris show off their incredible beach bodies while enjoying a fun day with their kids in Melbourne.

Rebecca Judd and her husband Chris enjoyed a fun day with their kids at the beach on Saturday.

The AFL WAG shared a series of photos on Instagram as she showed off her incredible physique in a sleek barely-there two-piece suit as she relaxed on the sand.

The 41-year-old flaunted her slender figure in a crinkled red bikini and protected herself from the sun with a cowboy hat.

Bec also posted a photo of her husband Chris playing ball in the water with their two children.

Chris, 40, showed off his muscular body as he tossed a tennis ball with his sons, who were wearing identical swim trunks.

“Triplets,” Bec captioned the photo, adding, “And yes, my husband is hot.”

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

It comes after Bec recently sparked fears she was “too skinny”.

Concern over the model’s physical appearance arose after Bec posted photos of herself wearing a vibrant yellow outfit last week.

In the images, the stunner showed off her very slender figure in a two-piece set from Elyia The Label.

The conversation about her figure began on Facebook when a user commented that she looked ‘too bony’, which sparked a series of reactions.

Another chimed in writing “for the love of God, give him a good feed.” A third echoed it with comments including “give him a burger” and “buy a happy meal.”

However, others stepped in to defend Judd.

“She looks good, only couch potatoes will despise her because they can’t give up the chips,” said one, suggesting the criticism came from envy.
