We have more information for you on the birth of Beyonce’s first child from TMZ.com, and our Lenox Hill hospital source.

According to our source, Beyonce and her surrogate were admitted to the upper East side hospital on the same maternity floor. Other women in labor were also admitted to the floor despite rumors that Beyonce and Jay Z rented the entire floor for an absurd $1.3 million.

Our source said, “Lenox Hill does not turn away expectant mothers to cater to the needs of celebrities.”

The NY Daily News confirmed that Beyonce was admitted to the hospital under the name Ingrid Jackson. But we’re told the surrogate mother was also admitted to Lenox Hill under an assumed alias.

According to TMZ.com, hospital brass held a meeting leading up to the delivery to discuss a security plan for the birth. The meeting between execs and security was held Friday afternoon and strict security was in place almost immediately, preparing for the Saturday delivery.

Such an elaborate security plan was required to conceal the fact that Beyonce was not the one giving birth. Security cameras were taped over, or turned off — which is a violation of hospital policies.

Our source said the baby girl was delivered via c-section while the mother was given an epidural to block the pain. The birth mother was allowed to briefly hold the baby and then the baby was handed off to Beyonce who waited in an adjoining room.

The hospital source said Beyonce declined to be present in the delivery room during the birth. The baby’s name, Blue Ivy Carter, was chosen prior to her birth. It is presumed that the name is an amalgamation of Jay Z and Beyonce’s albums, Blueprint and 4 since IV is the Roman numeral symbol for the number 4.

Mystery and rumors surrounded the “pregnancy” of one of the most narcissistic pop singers in music history. Beyonce performed 4 sold out performances wearing a skimpy outfit in New York just 10 days before showing up obviously pregnant on the red carpet at the MTV Awards.

Since that time, Beyonce’s baby bump took on various shapes and sizes, and even appeared to collapse completely during an interview on an Australian TV show.

According to to our source, the birth mother will be secreted out of Lenox Hill hospital sometime Tuesday or Wednesday. Meanwhile, Beyonce will leave the hospital with the baby under heavy security either Monday or Tuesday.
