Kim Kardashian wants to lose another 10 pounds.
The Kourtney and Kim Take Miami star - who recently dropped six pounds after gaining some extra weight since she began dating rapper Kanye West in April - is eager to tone up and is working out more than ever. A source told USMagazine.com: "Kim wants to lose 10 pounds."
The insider revealed that the 32-year-old reality TV star - who has worked with celebrity trainer Gunnar Peterson for years - is now also working with Gwyneth Paltrow's fitness guru Tracey Anderson, as she is terrified of putting on more weight over the festive season.
Tracey - who is also responsible for keeping Courtney Cox, Ashley Greene and Nicole Richie in shape - is well known for her intensive two hour workouts, which incorporate dance and light weights.
According to the source, Kim began working with Tracey on November 5 and plans to travel with one of her approved personal trainers so she can work out every day.
Earlier this year, Kim revealed she wanted to slim down after relaxing her diet because she is so happy with Kanye, 35, and they spend a lot of time eating in nice restaurants.
But the brunette beauty is determined to keep her most of her curves.
She previously said: "You have to really know your body. Everyone has a body part that they don't like and want to conceal, and something that they like and want to show off. So it's all about knowing what you want to show." Kim's younger sister Khloe, 28, recently admitted she is hoping to tone up as well and is currently on a new X Factor diet because she wants to look good on the series, which she co-hosts alongside Mario Lopez.
