Beyonce and Jay Z's twins are reportedly receiving treatment for jaundice after being born prematurely.
Family insiders told TMZ the boy and girl, who have been in hospital since their birth eight days ago, are "under the lights" - a common treatment for jaundice.
TMZ reported yesterday that the newborns have spent the week in hospital with a "minor issue" because doctors don't "feel comfortable" releasing them.
However they are expected to be okay.
On Sunday, which is Father's Day in the US, Beyonce's dad confirmed the arrival of his daughter's babies.
