(Yahoo!) - Everyone's jaws dropped on Wednesday morning after they saw how fabulous Kim Kardashian's post-baby beach bod looked on Us Weekly's latest cover - hat is, everyone's jaw except for Kim's.

"Omg! Insider's" Thea Andrews caught up with the reality star Wednesday morning at The Hollywood Reporter’s 22nd annual Women in Entertainment breakfast presented by Lifetime, where - proving that she's her own harshest critic - she revealed that seeing that picture only made her want to work harder in the gym.

"I don't know if I really love that shot," Kim confessed.

"You worked really hard for it though, and you're being recognized for it," Thea replied.

"I'm so critical of myself, so I look at it [and] I'm like, 'Alright I have to get back in the gym, don't slack for the holidays,' after seeing that," noted the 33-year-old beauty. "And I'm like, 'I have a couple more [pounds] to go.'"

Kim also opened up about how focused she was on whipping her physique back into shape after having given birth to daughter Nori in June. "It just feels good for me that I really was never a dieter and I could never stick to anything. I had more will power, so I think because of so much media scrutiny it really motivated me actually … to want to really stick and commit to something," she continued.

"And after like six weeks for the doctor to say you can start working out and dieting, I really stuck with this. So I was really proud of the accomplishment that I stuck to a diet that before I was never able to do."
