Beyonce made her second post-baby appearance yesterday, dazzling once again as she attended the last night of hubby Jay-Z's Carnegie Hall benefit concert. 

The 30-year-old diva stunned everyone on Monday -- the first time she stepped out since giving birth to daughter Blue Ivy Carter. The same was true for last night, when Beyonce wore a form-fiting Monique Lhuillier black sequined cocktail dress and Gucci shoes, complete with a Chanel purse. Of course, her jewelry -- by Lorraine Schwartz -- and her nails, were Blue.

Beyonce and Jay-Z once again headed to the 40/40 club for the after-party.
