After winning a Grammy award this past Sunday Blue Ivy was seen sporting a plastic crown that used to belong to Biggie Smalls and was sold at an auction for $500k. The 9-year-old star celebrated her Grammy win by sipping some juice out of the coveted award. It doesn't get any more boss than that!

On Sunday Blue Ivy, 9, was stuntin' like her mama after successfully nabbing her first Grammy. During the pre-telecast ceremony of the 63rd annual Grammys Awards, Blue, Beyoncé, and WizKid won Best Music Video for “Brown Skin Girl.”
