Three corners provided the Rossoneri's three goals. Alessandro Nesta prodded home Andrea Pirlo's cross at the far post in the first half, while Ronaldinho clinched the three points with 20 minutes to go with a glancing header, again from a Pirlo corner.
The Brazilian made it three in the closing stages, chesting down David Beckham's cross and finishing superbly past Juve 'keeper Alex Manninger.
The result keeps Milan in second, and underlines their status as the likeliest challengers to Jose Mourinho's Inter. Juve remain third, 12 points behind Inter, and four behind Milan.
Juventus had the better of a disjointed first half hour, in which misplaced passes dominated. Brazilian playmaker Diego was the only man who looked capable of providing the spark that would bring the match to life, and that almost proved the case as he cut in from the left, wrongfooting Gennaro Gattuso, before curling a right-foot effort just past the far post.
Uncharacteristically poor delivery from David Beckham meant nothing came from a series of Milan corners, though Andrea Pirlo's first corner of a game brought about the game's opening goal on the half-hour mark.
The Milan playmaker's cross should have been routinely booted clear at the near post by Felipe Melo at the near post, but he somehow missed the ball, allowing Nesta to pounce at the far post.
With the Rossoneri keeping the ball beautifully at the start of the second half, Juve coach Ciro Ferrara threw on Alessandro del Piero on 60 minutes in place of the anonymous Hasan Salihamdizic, while Christian Poulsen was almost immediately stretchered off and replaced by de Ceglie.
A free-kick blazed wastefully over the bar was the sum total of Del Piero's impact, and though Milan looked rather toothless in open play, they doubled their lead through another Pirlo set-piece with 20 minutes to go. Ronaldinho met Pirlo's corner at the near post with a glancing header, though it took another small but vital deflection off De Ceglie on its way in.
