Beyonce made a surprise appearance at Target in East Harlem, joining kids from a local Boys & Girls Club on stage to perform her latest hit, “Countdown.”  Fresh from her whirlwind tour of London (B closed last weekend’s Glastonbury Festival and appeared on Piers Morgan Tonight), Beyonce’s drop-in marked the one year anniversary of the location’s Target.

This is great practice for when Beyonce plans to have children take her diva ‘tude (which is a good thing) to the next level, as she mentioned to Piers Morgan.  “I feel like a woman. I feel like I’m very aware of who I am. I feel great and I feel like 30 is the ideal age [to start a family], because you’re mature enough to know who you are and to have your boundaries and your standards, and not be afraid, too polite — but you’re young enough to be a young woman. I’m so looking forward to it.
