A father has been left fuming after Beyoncé's security allegedly prevented him seeing his premature twins born in the same hospital as the star's daughter, Blue Ivy Carter.

Neil Coulon, 38, of Brooklyn claims that his stress levels multipled threefold when Beyoncé's bodyguards repeatedly barred him from the sixth-floor neonatal intensive care unit.

The contractor told the New York Daily that the security treated the Lennox Hill hospital in New York, where the 30-yaer-old star gave birth by scheduled caesarean section on Saturday night, like a 'an exclusive nightclub'.

He complained that the heavy handed security also cleared a waiting room and sent his relatives packing.

Coulon said: "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.

"They should have been more strategic about it. These are children with problems in intensive care and you're just going to take over the hospital like you own it? All I want is an apology," he added.

The star and her rapper husband Jay Z reportedly spent $1.3 million (£842,000) to seal off and redecorate a wing in a bid to protect their daughter from any media intrusion.

But Coulson insisted that he was not pleased with the clear double standards and complained that he was worried about his wife's well-being.

"My wife is just terribly upset. She had a C-section. She gave birth to twins. She is sore. Nobody needs this.

"This is the NICU. Nobody cares if you're a celebrity. Nobody is star-gazing. They just want to see their children. To have that circus roll into town and ruin our parade was unpleasant," he said.

However, the paper reports that hospital is yet to receive an official complaint.

Lennox Hill spokeswoman Anne Silverman said: "We take patient satisfaction very seriously. This is the first time I'm hearing about it."
