Kim Kardashian had a pregnancy scare late Tuesday night. The new millennium socialite was rushed to a hospital thinking she was having a miscarriage, The New York Post reports. Though it was only a scare, doctors have ordered the singer to reduce her stressful schedule and rest more.

Though nearly half-way through her pregnancy at 4 months, Kardashian hopped on a plane to Paris last Sunday to join Kanye West for a Givenchy fashion show. The couple had dinner with some friends after the show: outspoken R&B artist Frank Ocean and Italian fashion designer Riccardo Tisci.

All was apparently fine in Paris, but when the plane landed Kardashian was immediately taken to the hospital. The reality star was reportedly in tears.

"Kim started feeling ill on the plane from Paris, and called friends as soon as she landed," a source close to Kardashian said. "She was rushed to her doctor Tuesday night in tears. She thought she was having a miscarriage."

Fortunately for the Kardashian family and baby-daddy Kanye West, the baby was fine and healthy. The E! vixen was released from the hospital at 12:30 a.m., Wednesday morning, after being examined and given two thumbs up. Doctors were concerned, however, about Kardashian's busy lifestyle, claiming she may be working and exercising too hard, and could jeopardize the baby's health. Doctors sternly warned Kardashian to take some time off, stay home and rest.
