Kim Kardashian was reportedly rushed to hospital on Tuesday night.

The Keeping Up With the Kardashians star - who is expecting her first child with boyfriend Kanye West - was taken ill on a flight back to Los Angeles from Paris and rushed straight to a medical facility amid concerns for her unborn baby.

"Kim started feeling ill on the plane from Paris, and called friends as soon as she landed. She was rushed to her doctor Tuesday night in tears," a source told The New York Post.

After being examined, Kim was given the all-clear by doctors at around 12:30 am and ordered to rest as medics are concerned she is working and exercising too hard. "Kim's not respecting her pregnancy. She's running around, working out seven days a week. She's working with two different trainers to control her weight, including Tracy Anderson and a pregnancy trainer. She's scared that her ass is as big as a couch and is going south. But she is having a very rough pregnancy, and doctors have ordered her to slow down," another source said.
