And just like that, she was gone. After giving birth over the weekend at a New York hospital, Beyoncé and her newborn made a quick exit in the middle of the night without a single photographer snapping a photo of them.

The 30-year-old singer quietly checked out of Lenox Hill Hospital after delivering her daughter Blue Ivy Carter on Saturday night.

According to the New York Daily News, a procession of vehicles with blacked-out windows carrying the famous couple and their child departed from the hospital’s side gate in the early hours of Tuesday morning.

The operation was performed smoothly and swiftly so that no paparazzi could capture a photo of the family.

Two black SUVs left the hospital’s loading dock at 1:30 a.m. Soon after, a van parked on a nearby corner backed into the same loading dock before the gate closed, reopening minutes later. The vehicle drove out and headed north on Park Ave.

One of the two SUVs blocked traffic so the van would not be stopped. The second SUV pulled in behind the van to prevent anyone from following the Carters as they returned home with their baby.

“Immediately, security personnel began leaving the hospital,” said one witness, describing the exit as “very precise, very military-like.”

Beyoncé checked into the hospital on Friday night using the alias Ingrid Jackson. Blue Ivy was reportedly born in an executive suite on the sixth floor, near the neonatal intensive-care unit.

The hospital shot down rumors that Beyoncé and Jay-Z paid to close off the entire maternity wing. “The suggestion that the couple paid $1.3 million to rent an entire maternity floor is simply not true,” said Lenox Hill Hospital Executive Director Frank Danza.
