Australian fashion designer Kym Ellery has dismissed reports that romantically linked her to actor Joel Edgerton.

Edgerton, who has starred in movies such as Star Wars and Ned Kelly, was believed to be dating Ellery after a fashion insider said they had struck up a "relationship".

Ellery told The Daily Telegraph: "We're friends, but we're not dating. I am single, happily."

Edgerton is believed to be single since a rumoured romance with his Waiting City co-star Isabel Lucas earlier this year.

The designer is currently working on her next Ellery fashion collection in Paris.
