Beyonce's sis' Solange often lets her pop superstar sibling look after her five-year-old son Daniel because she's so good with him.

She said: "Beyonce'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."

Singer Solange also revealed: "[Beyonce] actually requests him more than I'm willing to give him. But the bedtimes we got to work on. Sometimes I'll call expecting him to be asleep, but he's still up!"

Teehee... he's probably practicing dance moves with his Aunt Beyonce!
