NEW YORK (AP) -- New York health officials are investigating complaints patients in a hospital neonatal unit were mistreated while Beyonce and Jay-Z were there giving birth to their daughter.

Health department spokesman Michael Moran says they received two complaints about Manhattan's Lenox Hill Hospital.

Jay-Z and Beyonce gave birth to their daughter, Blue Ivy Carter, on Saturday.

Media reports said the couple paid $1 million to take over a floor and their security guard blocked parents from the neonatal unit for hours. The hospital denied the reports, saying the couple paid the standard rate for an executive suite without disclosing what that is.

But hospital spokeswoman Barbara Osborn said Wednesday the hospital's executive director was conducting an inquiry into the complaints about treatment of neonatal unit patients.
