Blue Ivy Carter, 9, can dance just like her mom, Beyonce Knowles-Carter, 39, and her aunt, Solange Knowles, 34! Tina Lawson, Blue Ivy’s grandmother, posted an epic Instagram video on Jan. 10 of Blue Ivy dancing during a dance class. “Thi [sic] is Blue but I swear it looks like Solange dancing at this age,” Tina captioned the video.
