Beyoncé and Jay-Z gave birth to their little girl on Saturday night, January 7, in New York's Lenox Hill Hospital, and Neil Nash-Coulon tells The Insider that Beyoncé and Jay-Z's bodyguards were treating the sixth-floor neonatal intensive care unit like they owned it, repeatedly barring the non-celebrity couple from seeing their own premature newborn twins.

"The security presence was kind of heavy, and they weren't really gracious with their actions towards people; they were just kind of hammering people wherever they wanted them to go," Neil tells The Insider's Christina McLarty. He says that at one point, when they were attempting to leave the hospital, they were informed by security, "You can't leave for 20 minutes because we're using the hallway to transport hazardous materials."

"There are a lot of tiny babies here and a lot of concerned parents, and maybe this isn't the best place to be hiding people," continues Neil. "Everybody failed to do a good job."

Neil says that he and Rozz Nash-Coulon were not the only ones hassled by Beyonce's security, recalling that one father "didn't get to see his child for three hours. That's wrong. That's really wrong."

"It was like we were treated like children, that we couldn't handle the information," says Rozz, adding with a laugh, "We don't really care about celebrities there. … You know, everybody had a child in there. … We all had a special event, and I just wished they would have acknowledged that and had, across the board, just sort of equality in terms of care and consideration for the people who are having babies there."

Beyonce and Jay-Z reportedly paid $1.3 million to seal off a wing in the hospital -- and also redecorate it -- to protect their privacy, but a hospital rep said in a statement, "No security plan that we or the Carters' security team put in place would have prevented or delayed families from gaining access."
