Music power couple Beyonce and Jay-Z don't have kids of their own just yet, but they're getting plenty of practice thanks to the Single Ladies singer's 5-year-old nephew Daniel.
Daniel's mom Solange Knowles gives both babysitters rave reviews, telling OK! that Jay-Z is a "very good uncle." As for her big sis Beyonce:
“She’s very hands-on. I’ve had two weekends where I’ve been able to hand him over, and it’s been very nerve-racking for me, but she does a great job. The bedtimes we got to work on. Sometimes I’ll call expecting him to be asleep, but he’s still up.”
