"Jay rents a luxurious basement suite for $1 million a year," a source says in the new issue of of Us Weekly, on stands now. "It has an area for Blue filled with toys."
Jay's VIP space — the priciest of 11 spreads for rent (average cost: $550,000) — also serves as an adult playground. "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."
In October, Beyonce helped Jay-Z close out his eight performances at the Barclays Center as a surprise guest. Blue's parents, who wed in April 2008, performed "Crazy in Love" together, and shared a kiss on stage.
"Of course I had to let BK touch the stage in BK," Jay-Z joked to the audience. "Well, BKC now."
Beyonce kicked off the new year with a private performance in Las Vegas. "In our perfect ways, in the ways we are beautiful, in the ways we are human — we are here," she wrote in a handwritten note on her Tumblr blog. "Happy New Year's. Let's make it ours."
