Katharine McPhee in Theysen’s Theory at Golden Globe Awards

Holy sexy McPhee! Katharine McPhee sizzled on the red carpet in a black body bearing dress from Theysken’s Theory for the Golden Globe Awards.  This gown was a major step in the right direction for the Smash actress, who has vamped up her style quotient.  Can this be the work of a new stylist? Or perhaps designers are willing to loan her better pieces? Regardless of the reasons for her style improvement, we are giving her two big thumbs up.  The gown had a deep plunge in the front, tastefully showing off her decolletage.  It went further to reveal more skin with a thigh high slit.  Sexy!
