How proud Zac Efron and Nick Cokas must be of their women.
In the picture below, Vanessa Hudgens sings a tune alongside American Idol alum Katharine McPhee. Ne-Yo is the lucky gentlemen who graces the stage alongside these talented beauties, as they gathered over the weekend to film TNT's Christmas in Washington 2007 at The National Building Museum in Washington, D.C.
Vanessa Hudgens and Katharine McPhee represent High School Musical and American Idol, respectively. Ne-Yo? He just represents pure sexiness.
Other artists slated to perform on the special, which airs December 12, are: Alan Jackson, Andrea Bocelli, Colbie Caillat and Heather Headley.
Shockingly, the event did not ask another past American Idol finalist to take part on in it. Jessica Sierra must be crushed. And in jail.
