Beyonce Knowles and daughter Blue Ivy Carter

Blue Ivy Carter has a $1 million nursery under the Barclays Center, a report has claimed.

The Barclays Center is the arena where the Brooklyn Nets play their home games during the NBA (National Basketball Association) season.

While Jay-Z and wife Beyonce Knowles are watching their team play, they can drop off celebrity baby Blue Ivy at the suite.

"Jay rents a luxurious basement suite for $1 million a year," a source revealed to Us Weekly.

"It has an area for Blue filled with toys."

Jay-Z has figured out the space is not bad for adults as well - if Blue Ivy stays home, he can use it as a party suite for his pals.

The space does double-duty as a hangout for Jay’s adult pals, the report states.

“It’s all glass with a champagne bar and TV screen,” says the source.

“Jay lets friends use his digs when he’s not there.”
