The British actress and model attended the InStyle and Warner Bros. after party alongside her latest co-star Elisha Cuthbert on Sunday night (11 January), rather than other half David.
It was reported in this weekend's Sun on Sunday that Kelly and David had called it quits once again while holidaying together in Australia recently.
A source claimed Kelly had flown straight home after it ended.
But, at yesterday's Golden Globes after-party, the starlet certainly didn't look broken hearted as she posed for the cameras with a big smile on her face.
Kelly's the star of a brand new US sitcom called One Big Happy, which also stars former 24 actress Elisha.
The plot revolves around a man and his lesbian friend who decide to have a baby together – except he then falls in love with another woman (played by Kelly) which makes things very complicated.
One Big Happy premieres Tuesday, 17 March in the US.
Meanwhile, Kelly and David have yet to confirm the latest split rumours.
They became engaged in March last year after a whirlwind romance but split that September. They then reunited briefly before separating again in November.
But in December, it was once again rumoured they were back on again, thanks to a date night at Winter Wonderland. They also spent the festive season together in Sydney, Australia.
