Beyonce, Jay-Z and Blue Ivy Carter made their public debut as a family in New York City on Saturday, when they were spotted out to lunch at Sant Ambroeus Restaurant in Manhattan's West Village, media reports said.

Blue Ivy was born in January. Beyonce, 30, was seen holding her daughter in a blanket as she left the restaurant. Beyonce looked quite comfortable in a pair of leather pants, boots and a navy blue jacket.

On Sunday, Beyonce was seen out again with Blue Ivy, taking a stroll around the city with her body guard close by. (See the photos here.)

Earlier last week, Beyonce and Jay-Z, 42, took in a basketball game at Madison Square Garden. They are among the growing list of celebrities checking out the Knicks' new point-guard sensation Jeremy Lin.
