Beyoncé and Jay-Z are the proud parents of a baby girl. The couple welcomed a daughter on Saturday night in New York, according to various reports.

The baby was born via scheduled C-section. E! News reports that her name is Blue Ivy Carter, but this has yet to be confirmed by the couple’s reps.

Rihanna was among the first to congratulate the new parents. “Welcome to the world princess Carter! Love Aunty Rih,” she tweeted.

Russell Simmons also chimed in with his well wishes. “congrats to my good friends Beyonce and Jay-Z.”

There were rampant rumors that Beyoncé had given birth before the new year. But the singer was spotted just days ago in Manhattan

The Daily News reports that Beyonce checked into NYC’s Lenox Hill Hospital on Friday night, taking over an entire floor of the labor and delivery department:
Hospital workers placed tape over security cameras and are forcing employees to turn in cell phones when they arrive for their shifts, the source said. Several security guards were spotted patrolling the outside of the hospital Saturday night.

A Lenox Hill staffer confirmed that a patient named Ingrid Jackson was in a “labor room.”
