The second season of Khloe Kardashian‘s E! reality series Revenge Body premiered on Sunday night, and she live tweeted throughout the episode. While the show follows contestants on transformational journeys with Hollywood trainers and glam squads, Kardashian couldn’t help but reflect on her own figure.

“Side note: My jaw line was so good! lol now I’m getting a double chin,” Kardashian tweeted mid episode, while watching her pre-pregnancy self on screen.

The soon-to-be mom is currently expecting her first child with boyfriend Tristan Thompson and is six months along. Seemingly, she’s struggling to come to terms with some of the ways her body is changing. Although the 33-year-old still looks amazing, it’s no secret that pregnancy takes mental and physical adjustments — both aspects of her health that she’s been working on since her split from ex-husband Lamar Odom.

Kardashian’s split from the former NBA player led her to seek stress-reducing activities and workouts, which began her weight loss journey. She tells E! that the title of her show is a play off of the remarks people made to her about a good body being the best revenge against an ex, and now integrates that message into contestants’s various struggles, although she’s beyond her own.

In an Instagram post leading up to the show’s season premiere, the reality star posted transformation photos of herself and acknowledged the difficulty in doing so, writing, “I can’t imagine my life being this unhealthy again. Never would I ever consider myself fat, But I would consider myself unhealthy mentally/physically and not knowing my true value. Mind, body and soul.”

In the past few years, the youngest of the Kardashian sisters has been outwardly motivated to keep up with her fitness — posting to her social media channels, as well as her app, about her workouts and clean eating habits. Even sister Kim Kardashian West started documenting her sessions with a personal trainer and has worked to get into the best shape of her life post two pregnancies which took a toll on her physically. Back in August 2016, the mother-of-two wrote a post on her app about how she struggled with body image, especially while pregnant with North.

“During my first pregnancy, I just wanted to cover up,” Kardashian West wrote. “I wasn’t used to how being pregnant made me feel, and I honestly had a hard time being comfortable with it. I was so jealous of women who had these cute little baby bellies and would gain 25 pounds — and then, a few weeks after giving birth, somehow look exactly like they did before they were pregnant, lol. That’s not me.”

According to People, the reportedly pregnant Kylie Jenner is feeling the same. The 20-year-old has yet to make a public appearance through the months of pregnancy speculation, or confirm it herself, and a source told the outlet that it’s because of her body.

“Her body is changing and she’s very self-conscious about it,” the source said. “She’s always been insecure that she’s not as curvy or pretty as her sisters.”

For the Kardashian sisters that we have seen pregnant, however, their fashion has not suffered from any changes. Kourtney, Kim, and now Khloe have all slayed their maternity looks — although Khloe recently told Ellen she’s trying to stay out of the maternity clothing section for as long as she can.
