Before they were famous models, Gigi and Bella Hadid were making appearances alongside their mother on The Real Housewives of Beverly Hills — and Bravo won't let them forget their reality show roots.

Much to their fans' delight, the network shared a mashup of the sisters' scenes on the series earlier this month, including cringeworthy footage of their mom, Yolanda Hadid (formerly Foster), schilling out dieting advice and discouraging Gigi from playing volleyball because it will make her 'bulky.'

'Volleyball is a very masculine sport. Modeling a very feminine thing,' Yolanda tells the then-17-year-old while preparing dinner for her family in the season three episode that aired in 2012.

Superstars: Bella and Gigi have become two of the most famous models in the world since their time on the show

Yolonda, who was a famous model before she became a mom, is brutally honest with her daughters about what it takes to succeed in the cutthroat industry.

Stage mom? In many of the scenes, Yolanda, now 55, is reminding Gigi to stick to her diet

In her testimonial, the mother-of-three, explains that her eldest daughter wants to be a model, but she is suddenly missing the time she spent playing volleyball.

'She's gotta start building her career and that means sometimes we have to give up the things that we love to do,' Yolanda tells the camera.

'These girls they train four hours a day after school so their bodies are big and bulky. I mean, they eat like men. I wanted her to develop as a woman.'

Gigi, who is now 23, recalls how she used to wear basketball clothes to school every day when she was in the third grade.

Then and now: Gigi was 17 years old and just starting out as a model when she first appeared in the show. She still has the same long blonde hair she had before she was famous

Transformation: Bella looked completely different when she was 16 years old. Rumors have swirled for years that she's had plastic surgery, but she has vehemently denied the claims

'I thought that my daughter was a . . . lesbian,' Yolanda admits.

In another scene, Yolanda and Gigi are on set at one of her photo shoots. The teen is getting ready to celebrate her birthday, and all she is looking forward to is breaking her diet.

'I am so excited for the food,' she tells her mom. 'Pretty much all of the food that we are eating is a like heart attack in a meal, but it's going to be so good.'

Yolanda doesn't say anything about her daughter letting loose on her birthday, but she does warn her that she needs to stay thin in order to book work as a model.

'You can have one night of being bad, right,' she tells Gigi. 'Then you gotta get back on your diet because, you know, in Paris and Milan they like the girls just a tad on the skinny side.'

Yolanda is still talking about Gigi's diet in the next clip from season four, but this time she is praising her for her hard work.

Keeping it real? Yolonda, who was a famous model before she became a mom, is brutally honest with her daughters about what it takes to succeed in the cutthroat industry.

Background: Bella and her younger brother, Anwar, are also in the scene, but the focus is Gigi wanting to play volleyball again

'You are doing such a good job, Gigi,' she tells her while on a shoot. 'Aren't you proud? It's hard to exercise six days a week. It's hard to not eat any sugar, and it's hard to have to eat a salad every day, but now you see how it pays off.'

Although Gigi admits that she sometimes hates working out, she agrees that it is all worth it because she is so happy to be a rising model.

The majority of the footage focuses on Gigi and her budding modeling career, though a teenage Bella is present in some of the clips.

In one scene, Gigi and Bella are raiding their mother's closet before the eldest Hadid's trip to London for a shoot with Grazia magazine.

'It's cute when you have girls the same size as you are,' Yolanda says in her testimonial. 'So now they can borrow things from me, but sometimes they don't bring it back. So that's not that cute.'

While Gigi proudly relays a conversation she had with a banker after depositing some work checks, Bella admits that she probably only has about $8 to her name.

Constant reminder: Gigi's diet becomes a topic of discussion at her graduation party after Yolanda surprises her with a cake with one of her modeling pictures on it

Uncomfortable: While Gigi insists she has to have a bite of cake for 'good luck,' Yolanda doesn't seem convinced by her logic

The next clip shows Gigi making a tearful speech at her graduation party, but the conversation once again returns to her diet after her mom surprises her with a cake featuring one of her modeling photos.

Although Yolanda got her a cake in honor of her big move, it doesn't look like she wants her daughter to eat it.

'This is the hardest for being on our diet,' she tells her daughter as she slices into her graduation cake.

'I have to have a bite for good luck though,' Gigi says, but Yolanda doesn't seem convinced by her logic.

'Um,' she says, and things only get more awkward when Gigi forces her mom to have a slice of cake as well.

Yolanda takes a minuscule bite before deciding she is done with it.

'Gigi's in charge of her own diet, but to be on your best weight you gotta make the right choices,' the momager explains in her confessional.

The following scene shows Yolanda moving Gigi into her first apartment in New York City. While Gigi was set on studying criminal psychology at The New School in the fall of 2013, her mom wasn't exactly on board.

'I always felt she should take a year off and just work and make as much money as she can, and she didn't want to,' Yolanda tells the camera.

The mom also explains that Gigi was supposed to have a roommate, but that fell through because the other girl's parents wanted her to live in a dorm with other freshmen.

'I didn't want Gigi to live in a dorm because I wanted her to be in more of a work environment,' Yolanda says. 'Kids party and go out and get drunk and I wanted her to really focus on her career where she has to get up at five in the morning and go to work and shoot all day. You know, that was important to me.'

Yolanda ended up getting her wish when Gigi suspended her studies to focus on her modeling career.

thoughts: The clips also had some people feeling bad for Gigi and Bella because of the way Yolanda monitored their diets and 'pushed' them into modeling at the start of their careers

Bella, on the other hand, wanted to focus on modeling from the get-go, but their mom was only willing to let her quit school if she was pulling in six figures.

In the final scene in the clip, Yolanda and her daughters are hanging out in Gigi's apartment and helping Bella pick out photos for her modeling portfolio.

'They are the black swan and the white swan, and obviously, as sisters that close in age there's always going to be competition, but Bella's going to do it her way,' Yolanda says of her daughters.

'When somebody's looking for a brunette with blue eyes, Gigi's not gonna get the job. If they are looking for an all American girl, they're not going to hire Bella,' she adds.

'I mean, it's just a big competitive business. If it's meant for them they are going to survive in it and be successful.'

The video has been viewed more than 3.5 million times, and some people took to the comments section to point out how different Bella looks at age 22 compared to when she was 16 years old.

'I still don't get how Bella is influencing an entire generation as a model with a complete face of surgery and no one talks about it,' one person wrote, while someone else commented: 'Bella’s face is totally different.'

All grown up: Many people pointed out that Bella looks completely different as a teenager than she does at age 22

Another added: 'And they try to say Bella had no plastic surgery to look how she does now.'

Since Bella started her modeling career in 2013, rumors have swirled that she has had a nose job and other physical enhancements, but she has vehemently denied the claims.

The clips also had some people feeling bad for Gigi and Bella because of the way Yolanda monitored their diets and 'pushed' them into modeling at the start of their careers.

'Oh my god her mom is scary... I would run away if I was Gigi' one person commented, while someone else admitted: 'I never really cared for Gigi or Bella but after seeing this... I feel so bad for them.'

'Wait this makes me really sad... like I'd have such horrible self-esteem if my mom treated me like that,' someone else wrote.

Gigi and Bella are now two of the most famous models in the world, and their younger brother Anwar, 19, is also a catwalk star.

Fans of their mother defended her behavior, insisting that she was just being honest with them about how the modeling industry works.

'If she didn't push, nothing would have come out the way that it did!' someone noted, while another person praised her parenting style.

'Good for pushing her child. Now they are all successful,' the fan wrote.
