Washington: Kim Kardashian, who is planning to debut her post-baby body later this summer on mum Kris Jenner`s talk show `Kris`, is reportedly getting antsy, as she is unable to reach her weight goal `fast enough`.
A source told Us magazine that the 32-year-old reality star is refusing to leave the house until she`s thinner.
The insider said that the starlet, who has already lost 20 of the 50 pounds she gained during her pregnancy, couldn`t lose the weight fast enough.
The source asserted that the new mum is frustrated that she can`t exercise yet, as the doctors have advised Kanye West `s girlfriend to take it easy for the first five weeks.
The insider added that the ` Keeping Up With the Kardashians` star really looks up to Beyonce, who debuted an impressive physique just a few months after the January 2012 birth of daughter Blue Ivy.
