The 32-year-old, who delivered her first daughter, North West, on June 15, is reportedly on a strict diet and exercising with her personal trainer daily in a bid to lose as much weight as possible before she steps out in public for the first time since giving birth, reported Contactmusic.
A source close to the 'Keeping Up with the Kardashians' star said that the brunette beauty "wouldn't stop talking about her body" in the delivery room and "she kept asking her sisters if she looked smaller and skinner after giving birth."
"Kim is obsessed with getting the baby weight off -- and fast. She really believes she can lose the first 30 pounds in the first month. She wants to look good in a bikini by the end of the summer.
She got so big. So now she wants to look as hot as possible." Despite working with celebrity trainer Tracy Anderson throughout her pregnancy, Kardashian is worried that her body will never look the same again.
