How cute! Katy Perry brough her grandmother, Ann Hudson, as her date to today's Billboard Awards. Seems that a love for sparkle runs in the family, with Ann carrying a glitter-encrusted cane down the white carpet to equal the bling of her grandaughter's sequin-strewn Blumarine lilac gown and diamond embellished bangle set. Adorable relatives aside, how do you feel about Katy's sparklicious gown?
