Beyonce & Jay-Z are still dealing with twins' premature birth

Beyonce gave birth 2 weeks ago Monday, but she and JAY-Z are still dealing with premature birth issues.

Sources familiar with the situation tell TMZ, as of 4 days ago the infants were still in the hospital. The twins are "under the lights" which typically means they have jaundice, the result of elevated bilirubin issues. The lights lower bilirubin in the blood to eliminate the jaundice.

None of the medical problems should pose serious long-term issues, nonetheless, doctors did not want the babies released until they were stabilized.

The star actress, Beyonce had a boy and a girl.

The release date is unclear.
