Beyoncé took to her blog on Tuesday to share more adorable photos [1] of herself and her daughter, Blue Ivy Carter, dressed up for Halloween [2]. The 2-year-old looked absolutely adorable as Michael Jackson [3], while her famous mom channeled Michael's sister Janet in her "Rhythm Nation" video [4]. 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 [5], with Blue Ivy in tow as Jay's mini-me. Scroll down and marvel at how flawless little Blue looks in her MJ costume.
