Kutcher apologises for online and radio rants

Ashton Kutcher has apologised to his neighbour for calling him a "jackass" and threatening to hi-jack his bulldozer in a building work meltdown.

The actor went online to complain about screenwriter Bruce Goldsmith's early construction work, which has been waking him up at 7am. He then took his grievances on air and called up DJ Ryan Seacrest's radio show to rant about his inconsiderate neighbour.
