Meanwhile, it has emerged that the A-list couple have infuriated other new parents by enforcing a lockdown at the hospital where they had their first child together.

The pop superstars reportedly spent a staggering $1.3 million for pricey renovations to an exclusive recovery area at one of Manhattan's swankiest hospitals - including a bulletproof door to her room.

They also have their own private security force working an area alongside hospital security already at Lenox Hill Hospital.

But other parents have bitterly complained that the intense measures have not just given privacy to the superstars and their baby - but made other new parents miss out on precious moments with their own newborns.

Fuming parents said they were essentially put on 'lockdown' so that the pampered songstress and her party could come and go as they pleased.

'They just used the hospital like it was their own and nobody else mattered,' blasted new dad Neil Coulon, who said his efforts to see his premature, newborn twins in the neonatal ICU were disrupted at least four times by the arrival of Beyonce and her crew.

Coulon - who is from Jay-Z's native Bedford-Stuyvesant in Brooklyn - said some of his relatives drove 4 1/2 hours to see his girls, only to be shunted aside for Beyonce.

'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!

Beyonce and Jay-Z have spent already spent the past two months supervising pricey renovations to Beyonce's mammoth, fourth-floor recovery digs - including the installation of a bulletproof door to her room, a hospital worker told The New York Post.

The windows in her reserved wing on that floor were darkened with what appeared to be special curtains or tape to prevent anyone looking in.

'Her room is bulletproof. It's custom-made,' a staffer said, noting that the couple sent in a security team 'a couple of months ago' to evaluate the accommodations.

'They came in and reconstructed it. It's completely different,'' said the employee.

But the real drama surrounding Blue Ivy's long-awaited arrival began Friday night, when Beyonce checked in under the name Ingrid Jackson and settled into her sixth-floor delivery suite to have the baby.

Windows in the NICU down the hall were blacked out with tape and temporary curtains so that nobody could see the comings and goings of the VIPs at the other end of the hallway.

Beyonce has 'her own security, and hospital security,' a Lenox Hill employee noted.

By last night, Blue Ivy and her mom had been moved back down to their special pad on the fourth floor, where the Grammy-winning new mom and rapper dad showed her off to friends, the employee said

Hospital spokeswoman Anne Silverman said she had not personally heard of the complaints.

'We take patient satisfaction very seriously,' Silverman said. 'This is the first time I'm hearing about it.'
