Matthew McConaughey is the slimmest he's been since high school.
And it isn't because the newlywed has his hands full with two young children and another on the way.
McConaughey's dramatic weightloss is for an upcoming role in "The Dallas Buyer's Club," in which the actor will play electrician Ron Woodroof, who contracts AIDS in 1986 and subsequently delves into the world of unapproved HIV drugs.
