Los Angeles, Feb 7 (IANS): Socialite Kim Kardashian, who is expecting her first child in July with rapper boyfriend Kanye West, is under stress because of her divorce battle with estranged husband Kris Humphries. She is worried it could have a long-term effect on her baby.

Kim split from Kris in November 2011 after 72 days of marriage.

A source told tmz.com that Kim, 32, was treated for severe abdominal pains in recent days, after her doctor rushed to her home in the middle of the night to examine her and warned her to reduce her stress levels.

She has been suffering from similar pains all week, including in the hours after her meeting with her divorce lawyer Laura Wasser Tuesday. Her friends insist the only significant stress is her life right now is her divorce.

Kim's mother and manager Kris Jenner confirmed she has been told to relax.

"Kim has been going through this divorce for months. She has been under a lot of stress because of it and the doctors told her she had a really tough week and the stress could become a problem if she isn't careful," said Jenner.
