Here’s Katharine McPhee, who once ruled this website along with her killer legs, performing on The Tonight Show with Conan O’Brien and dropping some serious cleavage while doing so. Hoochie mama! As I said, I was once infatuated with McPhee’s killer pair of legs, but they’ve been officially overshadowed by her fantastic cleavage, and I can smell a Katharine McPhee comeback in the air (well, at least here on Popoholic) if she continues to give shwingtastic performances such as this one. Enjoy the pictures and check out the video to see everything in motion. Cheers.
