London: Singers Beyonce Knowles and Jay-Z, who welcomed their first child together, reportedly caused havoc in the hospital during delivery.

The 30-year-old gave birth to a baby girl at Manhattan's Lenox Hill hospital on Saturday night and the couple rented out an entire floor for which they reportedly shelled out USD 1.3 million. However, on the delivery day, the couple decided to throw out other patients from the Neonatal Intensive Care Unit,  hich was on the same floor as Beyonce's delivery "suite", reports New York Post gossip column Page Six.

"They just used the hospital like it was their own and nobody else mattered," said Neil Coulon, whose efforts to see his premature, newborn twins in the neonatal ICU were disrupted by the birth of the superstar's first child.

"They locked us into the NICU and would say, 'You can't come out to the hallway for the next 20 minutes'. When I finally was able to go back out, I went to the waiting room and they'd ushered my family downstairs," Coulon added.
