Beyonce Knowles and Jay-Z have made a $100,000 donation to the New York hospital where they welcomed daughter Blue Ivy into the world.

The couple - who became parents for the first time last Saturday (07.01.12) - are said to have given a "very large" financial offering to Lenox Hill Hospital before the singer checked in to the facility's brand new "executive suite".

An insider told a media website: "Jay Z and Beyonce made a very large donation to Lenox Hill Hospital several months ago - the donation was at least $100,000."

The superstar pair have already splashed out more than $1.5 million on lavish gifts for their newborn daughter, including a $600,000 rocking horse, a $15,000 high chair and a $30,000 playhouse.

A source recently explained: "They're really pulling out all the stops - the two of them have been spending like there's no tomorrow! Together they've bought a Swarovski-studded high chair by Carla Monchen for $15,000, and a Fantasy 'posh tots' coach carriage crib for $22,000.

"Jay-Z bought Beyonce a solid gold handmade Ginza Tanaka rocking horse for $600,000. They've even splashed out on a $30,000 magical windmill playhouse for the garden and a mini Bugatti car, too."
