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

The star went online to complain about screenwriter Bruce Goldsmith's early construction work, which has been waking him up at 7 a.m. He then took his grievances on air by calling up DJ Ryan Seacrest's radio show to rant about his inconsiderate neighbor.

Hours later, the actor had calmed down enough to film a video in which he apologized to Goldsmith - and post it online.

He says, "You know, you're very vulnerable at 7 a.m... In light of reflection, I just want to say I pledge to be more tolerant of my neighbor's hammering in the morning as he tolerated the construction of my home."
