Beyoncé took to her blog on Tuesday to share more adorable photos of herself and her daughter, Blue Ivy Carter, dressed up for Halloween. The 2-year-old looked absolutely adorable as Michael Jackson, while her famous mom channeled Michael's sister Janet in her "Rhythm Nation" video. Beyoncé and Blue kicked off the holiday festivities when they attended Power 1051.1's Powerhouse event in NYC on Thursday; Jay Z took the stage to perform during the party, and the trio was spotted leaving together later that evening. The following day, the Knowles-Carter celebrated at the annual Halloween parade and dressed as iconic artists Frida Kahlo and Jean-Michel Basquiat, with Blue Ivy in tow as Jay's mini-me. Scroll down and marvel at how flawless little Blue looks in her MJ costume.
