Attending Elton John's annual Academy Awards after-party yesterday in LA, the British model made sure to dazzle on arrival in a figure-hugging floor length dress.
Kelly's gown (designed by Michael Cinco) featured an elegant white and nude design, as well as a pretty embellished scooped neck and train at her feet.
Oozing glamour, the 35-year-old let her dress take centre stage for the evening, tucking her long locks behind her ears.
To accessorise, Kelly added a touch of sparkle to her ensemble with a large diamond ring, matching bangle and drop earrings. She then completed her Oscar-worthy look with a slick of dull pink lipstick on her lips.
At the event, Kelly rubbed shoulders with the likes of Nicole Scherzinger, Miley Cyrus, Ashley Tisdale and Pitch Perfect star Brittany Snow.
No stranger to working the Hollywood party circuit lately, Kelly has often been spotted on the red carpet of events while promoting her new show One Big Happy.
Last year, the starlet relocated to LA to get started on the NBC sitcom and with filming all wrapped up, Kelly is now waiting for the show to hit US screens in March.
Ahead of its debut, fans have been given a sneak peek of One Big Happy in the show's trailer - and they definitely get more than they bargain for as Kelly features in the clip completely naked!
The show tells the story of an American man who decides to have a baby with his lesbian best friend. Things soon turn complicated though, when he meets Kelly's character and falls in love.
One Big Happy was produced by talk show host Ellen DeGeneres.
