The British model and actress joined her co-stars on the red carpet on Monday morning (12 May) at the NBC Upfronts Presentation.
Kelly, 33, was promoting comedy series One Big Happy. She had filmed a pilot for the half-hour sitcom earlier this year and recently got the good news that NBC had ordered a series.
One Big Happy stars 24 actress Elisha Cuthbert as a lesbian woman who gets pregnant by her straight best friend, played by Nick Zano.
Their family unit is then complicated by the arrival of Kelly's character Prudence, a gorgeous British woman who Nick's character falls head over heels for.
Kelly is clearly thrilled to be part of the show, tweeting from today's Upfronts: "Guess it's really happening...."
The Upfronts are part of the US TV industry calendar allowing a sneak peek at shows that have been commissioned for later in the year, primarily to allow advertisers the chance to buy advertising airtime early.
