Of course, now that she’s competing to portray the most famous blonde of them all on “Smash,” Katharine’s back in the limelight.

She’s featured in the June edition of Glamour magazine. She made the Sexy List for InStyle magazine’s June edition.

The 13-track album includes six other songs featuring Katharine.
