Calvin Harris faces law suit by his neighbour who has accused him of leaking dirty water out of his mansion

Calvin Harris is reportedly being sued by his Bel Air neighbour who has accused him of 'leaking filthy water' out of his sprawling mansion.

The DJ, 36, has apparently had water leaking from his home for the past year according to a a law suit obtained by Tmz, filed by Julie Opperman.

Opperman has reported that the leaking water from Calvin's property builds up on her driveway and access road and results in a 'muddy slime'.

The neighbour claimed in the suit that Calvin has previously been cited twice by the city over the mess, but his quick-fix was simply a 'band aid' for the problem.

Opperman alleged in her claim that Calvin has also failed to fix some fissures in his retraining walls which are directly above her property.

She has requested that a judge should force the media personality to fix the flowing water permanently and build a new retaining wall.
