{blackbabes} Beyonce and Jay-Z Increased Security Allegedly Kept Man from His Newborns

A Brooklyn man claims increased security at Lenox Hill hospital because the presence of Beyonce and Jay-Z kept him from seeing his prematurely born twins ... this according to a report.

Neil Coulon tells the NY Daily News he has been repeatedly kept out of the neonatal intensive care unit (NICU) by the couple's security. He also claims his relatives were booted out of the waiting room by bodyguards wearing headsets.

He tells the paper, "Three times they stopped me from entering or exiting the NICU and it happened once on Friday -- just because they wanted to use the hallway."

A rep for the hospital told the NYDN she hadn't personally heard of any complaints. We reached out for comment as well ... haven't heard back.
