Beyonce Knowles and Jay-Z had two private suites built at New York's Lenox Hill hospital to prepare for the arrival of their first child.

The couple - who welcomed daughter, Blue Ivy, into the world on Saturday -- reportedly had between six and eight existing rooms at the medical facility transformed into the luxury suites, which came complete with a whole host of lavish features including "mahogany walls".

A hospital source told US Weekly magazine: "A month ago, workers tore down between six and eight rooms and turned them into two suites. They paid to have it constructed just for them.

"You'd want to live in there!"

The superstar pair are already believed to have splashed out over $1.5 million on their newborn daughter, including a number of lavish gifts such as a $600,000 rocking horse, a $15,000 high chair and a $30,000 playhouse.

An insider recently said: "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 plashed out on a $30,000 magical windmill playhouse for the garden and a mini Bugatti car, too."
