Brittany Cartwright shows off her 40lb weight loss as she poses in a Fendi swimsuit

Vanderpump Rules veteran Brittany Cartwright showed off her post-baby body on Tuesday.

The beauty — who lost 40 pounds after welcoming son Cruz with husband Jax Taylor — wore a brown and black Fendi F-print one-piece bathing suit that hugged her curves.

She was on a boat on the water off the coast of Mexico’s Cabo San Lucas as she made her moves as a supermodel.

The TV star wasn’t alone, as she also shared a photo of friends taken from their backsides. ‘Is it still a thirst trap when you’re married? Cabooooooooo lol,” the model wrote in her caption.

This comes after she made an exclusive comment to DailyMail.com about Tom Sandoval’s cheating scandal when she launched her new collaboration with swimwear company Cupshe.

He caused a stir when he romanticized Raquel Leviss behind the back of girlfriend Ariana Madix.

‘I was very shocked!’ said Brittany last month. “The amount of betrayal that went into this affair is just so disturbing,” stated Brittany, who debuted her new swimwear collection with DailyMail.com on Monday.

And the pin-up revealed who she thinks will come out the best.

“Ariana 10000%!” she said, adding that Ariana seems happier without Tom, “I think you can already see that a huge weight has been lifted off her shoulders and I can see so many great things coming her way!” She deserves it,” she said.

This week, the 34-year-old Vanderpump Rules veteran spoke to DailyMail.com about her new gig for the company.

The beachwear brand is launching its 8th anniversary collection, BeMe: The Cupshe Birthday Collection in collaboration with Cartwright and Selling Sunset’s Heather Rae El Moussa, and model Chanel Iman.

Brittany shared that she’s been hitting the gym a lot lately after losing 40 pounds over the past year.

‘I trained hard. I love playing my favorite shows and going to town on the treadmill!” she shared.

“That’s a good trick to distract yourself and get a great workout at the same time!” she added.

Also in her interview, she spoke to husband Jax Taylor, their two-year-old son Cruz.

Her favorite workout is interval training. “You burn so many calories and running always helps me to stay calm. It’s also great for mental health. I always feel good after a good workout.’

And she’s dieting: “Intermittent fasting has also helped tremendously. Snacking has always been a problem for me, so I do my best to stop at some point.”

She also skips supplements. ‘I’m currently taking vitamins, but no supplements,” said Cartwright.

As far as working for Cupshe, she likes the cute and well-made suits.

‘They feel great! They support me in all the right places and make me feel confident and sexy,” she added.

Her favorite is the gold/metallic one. “It’s so cute and the bright pink bathing suit is such a great pop of color for summer.”

And she added that she’d like you to wear a bathing suit and jeans for a night out on the town, like Kim Kardashian does.

‘Absolute!! I like that look, it’s like a bodysuit, so why not?’

She also mentioned husband Jax Taylor whom she married in 2019. “I’m even more drawn to him after seeing him be such a great dad to Cruz,” she shared.

Brittany also spoke to DailyMail.com about being one new mother.

It’s the happiest she’s ever been,” she told DailyMail.com. ‘Having Cruz is by far the best thing that ever happened to me! I never knew such love existed. He’s the best ever.’

Be me; The Cupshe Birthday collection features 56 swim styles and 20 cover-up styles, ranging from size XS to 3X, and is divided into three sub-collections defined by each woman’s style.

“The collaboration with Chanel, Heather and Brittany is a reflection of the brand’s commitment to highlighting extraordinary, diverse women who break down barriers and inspire women everywhere to exude confidence and authenticity,” said a press release.

The collection released on June 5, 2023.
