Kim Kardashian has kept a very low profile since giving birth to daughter North West. No one has seen the baby girl and fans were only given a glimpse of the new mom from the chest up. According to new reports Kanye West's girlfriend is staying locked in her house until she can drop the last 30 pounds of her pregnancy weight gain.

According to the Daily Mail, a source revealed to US Weekly that Kardashian has already dropped 30 pounds but the last 30 has been really hard for her. The source claims she is "obsessed" with reaching her goal weight of 115 pounds.

"She's extremely self-conscious about her current body," the source told US Weekly. "She said when she comes out and gets photographed for the first time she wants to look hot, hot, hot."

The source adds that the "Keeping Up With the Kardashians" star is upset that the rest of the weight isn't coming off fast enough. It had been previously reported that she had enlisted the help of celebrity trainer Tracy Anderson to help her drop the weight and get her pre-baby body back.

"The weight is not coming off as quickly. She plateaued. This is the hard part now," a different source told the magazine. "She's always complaining about her size. She says she hates looking this way and won't go out again until she is skinnier."

To help her drop the weight  Anderson has the new mom on a strict diet and exercise regime. A source revealed that the trainer cooks her healthy food like grilled chicken.

The source also said it will probably take her about a month and a half before she is back to her goal weight and will probably remain out of the spotlight until then.  

"She thinks it will take her at least another month and a half to get to where she wants to be,' the source said. "Only when she's there will she start thinking about showing her body to the world."
