Kim Kardashian is reportedly "terrified she will never get her body back".
The 32-year-old reality star gave birth to daughter North West on June 15, her first child with her rapper beau Kanye West.
Apparently Kim will go to any lengths to drop the 60lbs she gained while pregnant, ignoring advice from her inner circle.
"Kim is obsessed with getting the baby weight off - and fast. She's terrified she will never get her body back," a source told In Touch magazine. "Everyone has told her not to stress - that it's about being healthy and having a good mind-set for your baby, not about losing the weight right away. But her family knows that at the end of the day, Kim will do what Kim wants."
Another insider notes Kim has high expectation for weight loss.
The star's fitness goals are said to be a little outlandish to some of her friends and family.
"She really believes she can lose the first 30lbs. in the first month," the second source revealed. "She wants to look good in a bikini by the end of the summer."
Throughout her pregnancy Kim posted sexy photographs of herself before she was expecting online.
According to a friend, her sisters Kourtney and Khloé constantly tease Kim about vain behaviour.
"She got so big. So now she wants to look as hot as possible," the pal revealed.
"Her sisters were making fun of her because she kept tweeting old bikini pictures of herself. They told her she needed to relax and enjoy the weight gain."
Kim and Kanye have been mocked for calling their daughter North West, with Kim's mom Kris Jenner defending the name earlier this week. The star's brother Rob has now followed suit, insisting it is the perfect choice for the tot.
"I told Kim and Kanye this, I'm like, 'Yo, people are always going to talk, whether it's good or bad. There's always going to be the haters, but do what you guys feel,'" he told radio host Ryan Seacrest "Like, you know everyone's going to say, 'Oh, you're coming up with some weird celebrity, crazy name.' You know how it is.
"[But] North West, it sounds cool! And North is the highest point, so it has a lot of meaning to it."
