She has a big weekend in New York City ahead of her, and Beyonce Knowles is already taking care of business like the seasoned pro that she is.

The “Irreplaceable” babe was spotted on her way out of Rockefeller Center last night (September 4) after wrapping up her rehearsal for the Fashion Rocks show.  She’ll perform at the event that will be taped tonight, and aired on Tuesday, September 9th.
