Katy Perry Resplendent at 2011 Grammy Awards

Katy Perry dazzled in a custom-made Giorgio Armani dress at the 2011 Grammy Awards at the Staples Center on Sunday, February 13 in Los Angeles.

Katy's dress had Swarovski crystal-encrusted bikini bodice and an elaborate mermaid skirt in white silk organza with sweeping train. The dress had white feather angel wings.

She accessorized with jeweled Casadei platform heels and Thomas Sabo jewelry.

The 26-year-old pop star looked hot enough to compel husband Russell Brand to kiss her on the red carpet. She, in turn, showered affections on her other date of the evening - her grandma, Ann Hudson, whom Katy brought to the event as a treat for her 90th birthday.

The trio was dressed in coordinating Armani outfits.

Granny's bejeweled cane was a birthday gift from the granddaughter.

Katy's red carpet drama doesn't end with her dress - her makeup too is always noteworthy. On Sunday, her thick kohl lined eyes had sparkling lilac eyeshadow on lids and green shadow under the eyes. Lovely pink lip color and wavy long black hair added to the oomph factor.

Katy Perry performed her songs "Not Like the Movies" and "Teenage Dream" at the show. During the performance a video recording of her wedding to Russell Brand in India came on as the backdrop, the first time ever the couple has shared the footage with the public.

Katy was a nominee for four awards but unfortunately she did not win any.
