Pregnant reality TV star Kim Kardashian has hired trainer Tracy Anderson to help her stay healthy and fit.

The 32-year-old' Keeping Up With The Kardashians' star, who is expecting her first child with rapper boyfriend Kanye West, is determined not to get fat while she is pregnant, reported New York Post online.

Anderson, who has worked with Gwyneth Paltrow and Madonna, said, "Kim is just so humbled but thrilled with this news of being pregnant. She wants her body to grow and expand. I don't care if she gains 40 or 70 pounds."

Kim is reportedly convinced she is expecting a baby girl and wants to name her Liv.
Friends say she has loved the moniker since she was a teenage admirer of actress Liv Tyler, plus one of her favourite Miami nightspots also has the same name.
