Hollywood hunk Keanu Reeves has hit out at reports that he secretly married his ex-girlfriend Autumn Macintosh last month in Los Angeles.

Several British newspapers had claimed the "Matrix" actor had a quiet civil ceremony at a small restaurant last week that was only attended by family and friends, reports celebrity portal Femalefirst.

Reeves, who dated actress Macintosh in the 1990s but later split with her, was rumoured to have rekindled their romance earlier this year.

The news sparked media frenzy because Reeves is reportedly dating his "Il Mare" co-star Lynn Collins and has been inseparable from her in the past few weeks.
