Watch Katharine McPhee Sing Rihanna's Cheers On Smash!

Guess they won’t be just sticking to musical numbers on the stage!
We approve!
Check out this brand-new, behind-the-scenes clip from the upcoming NBC series Smash, which features the show’s stars, Megan Hilty and Katharine McPhee, filming a fantasy musical sequence to the Rihanna hit Cheers (Drink To That) on the streets of Times Square (above)!
And producers Craig Zadan and Neil Meron reveal that if the show does well, the fictional Marilyn Monroe musical in which the story is centered will become an actual Broadway production!
So, so COOL!
We’ve only seen clips and we’re already obsessed!
Can’t wait for this one! How about U??
