Katy Perry [1] is officially engaged to Orlando Bloom [2]! The singer posted a picture of her engagement ring on Instagram with the clever caption "full bloom." Orlando got down on one knee [3] on Valentine's Day in a room surrounded by heart-shaped balloons. Katy's ring, much like her eclectic style [4], is truly one of a kind. Orlando chose a vintage flower-shaped ring that features a ruby centre stone and diamond baguettes as the petals. Get a closer look at her beautiful ring ahead.
