Real Housewives of Orange County star Emily Simpson, 50, stuns fans with unrecognizable new look after extreme makeover and weight loss

star Emily Simpson has shocked fans with her new look after embarking on a major health and fitness journey. 

The star, 50, looked completely different compared to her old self as she walked the red carpet at the season 20 premiere of the hit Bravo series in on Tuesday.

Simpson flaunted her slim yet muscular physique in a skintight red frock by Ronny Kobo, which featured cut-outs on the front to reveal a peek of her toned abs.

The former attorney's transformation sparked a firestorm on social media, with one fan calling her 'barely recognizable' following her recent and plastic surgery. 

'Emily you are such an I inspiration!! Gorgeous!' gushed one fan.

'Emily looks amazing! You can tell she has worked really hard. You are an inspiration,' wrote another. 

'You were always beautiful.. you didn't need to let television world change you,' a third commented. 

Simpson wasn't the only one Real Housewife causing a stir at the event, with original cast member Jo De La Rosa opting for a very daring ensemble.

The 45-year-old risked a wardrobe malfunction in a pink blazer with no bra or top underneath.

'Oh no, Jo, what are you wearing?' asked one shocked fan, while another wrote, 'Um, did someone forget their shirt?'

Tamra Judge, 58, and newcomer Carmella Garcia, 44, both flaunted their cleavage by wearing plunging gowns that left little to the imagination.

Meanwhile Vicki Gunvalson, 64, rocked a flirty gold mini-dress that cut off above her knees. 

Simpson has been open about using a combination of diet, exercise, cosmetic surgery, and Ozempic to achieve her sensational makeover.

She's had a number of tweaks over the years, including a breast reduction, a lower face and neck lift, liposuction on her arms, and injectables like Botox.

The reality star works out almost daily in the gym, primarily focusing on strength training, and uses Ozempic to control her cravings.

She recently gave an insight into her extreme transformation, citing a mix of GLP-1 usage and regular exercise.

'This is a ONE year transformation that was the result of: a GLP-1 PLUS seven days a week lifting weights in the gym combined with 20-30 minutes a day on the treadmill,' she wrote.

'More specifically, I normally do a daily treadmill workout of speed of 3.6 plus a 12-15 incline for 20 minutes followed by 40-60 minutes of lifting weights. I also added a lot of kettlebell workouts into my daily lifting routine,' she continued. 

'You’ve been asking… that’s the basic answer. No trainer… just me working out alone but I follow amazing and inspiring fitness influencers. I watch their content and save it and study it and learn and implement it.'

Back in 2023, Simpson told the Daily Mail that focusing on her diet was one of the biggest factors in her transformation.

'When I worked out for years before, I never changed my diet. I ate horribly. I was eating my kids' chicken nuggets, eating the rest of their mac and cheese. I never ever changed my diet,' she explained at the time.

'And when they say 80/20, it's true. It really is. So after I had liposuction in my arms and I had a breast reduction, aesthetically I looked completely different.'

Simpson said that she carries 'most of her extra weight' in her upper body, so she ended up looking significantly slimmer and more muscular following her lipo procedure and breast reduction.

'With all that gone, suddenly you could see all the muscles underneath that I'd been building for years,' she shared.

'I eat mostly protein now, I drink a tonne of water. I go to the gym six to seven times a week, and I work out hard. So that's what I've done.'

She added: 'People can say "Ozempic" all day long, and I don't deny it.'
