Some like it hot, indeed!

Katharine McPhee did her best Marilyn Monroe impression on the set of Smash Thursday afternoon in New York.

Though she was dressed in an oversized coat, cameras were still able to catch a glimpse of Katharine’s Marilyn, as the singer-actress donned a blonde wig and blue sequined dress. As if she could look any hotter!

Smash has fluctuated in the ratings since its premiere last month. This week, however, it rose 17 percent with about 8 million viewers tuning in.
