The British model and actress, 34, has landed a plum part in NBC sitcom pilot One Big Happy, alongside Hollywood stars Elisha Cuthbert and Nick Zano.
Kelly will play a pretty young British woman (not a stretch there!) called Prudence, who impulsively marries an American guy, partly because her visa is about to run out, reports Deadline.
She then gets sucked into her new husband's unusual relationship with a lesbian best friend, who he's just got pregnant as they both wanted a child.
Kelly met up with her soon-to-be castmates on Wednesday night, tweeting afterwards: "Cast bonding over a few Cocktails with @NICKZANO @HappyElishas Excited for our show One Big Happy."
So it's a been a pretty good year for Kelly then!
The star announced in March that she'd become engaged to former Royal Marine and Gladiators star David after twelve weeks of dating.
And, despite some critics suggesting it was too soon, her fiance's sister Angela has insisted the couple are perfect together.
Angela told this week's Reveal: "David is ready to settle down with Kelly, have a family and grow old with her. They both want kids and are both serious about their careers. I think they'll last the distance."
