Jennifer Lopez in Hospital After Miscarriage Scare

Jennifer has been ordered to rest by doctors over fears strenuous activity could put her unborn child in danger.

Jennifer Lopez was reportedly rushed to hospital following a miscarriage scare. The 'Do It Well' singer, who confirmed she is expecting her first child with husband Marc Anthony last week, was taken to a US hospital after noticing blood in her urine.

One of Jennifer's friends is quoted by various internet sites as saying: "She was worried that something bad could happen. She's petrified that something could go wrong with her pregnancy. The hospital visit really shook her up. If she lost the baby, her life would be shattered."

Jennifer, who has been touring North America with Marc, has been ordered to rest by doctors over fears strenuous activity could put her unborn child in danger. The 38-year-old singer's mother Guadalupe is said to have been begging Jennifer to slow down for months.

A source said: "Her mother is constantly on the phone, telling her to calm down. Guadalupe's very no-nonsense and she's told Jennifer that she needs to take some time out of the limelight to enjoy her pregnancy and her baby when he or she arrives."

Last week, the Latino star ended weeks of speculation by telling fans at her Miami concert she was pregnant. She said: "Marc and I are expecting!" Marc, who has three children from two previous relationships, then tenderly kissed her expanding stomach.

Reports of Jennifer's pregnancy first surfaced in September and she is thought to be due to give birth in the spring.
