COWELL TAKES SHOT AT ARCHULETA’S DAD IN CRITIQUE

On Tuesday night, Simon Cowell lashed out at someone after David Archuleta's performance, and we know who.

A well-placed TMZ spy tells us Simon went after David's dad, Jeff, for the kid's song, "You're the Voice" by John Farnham. Simon said, "I don't think that is you at all and I'd be amazed if you chose the song yourself." Our spy says Simon was blaming the fiasco on daddy dearest, adding, "It's exactly where the gun was being aimed."
