Just because we who are filling up PopWatch on this Christmas holiday—that’d be me and Michael Slezak!—idolize Vanessa Williams, we’re including a holiday performance of hers on the blog today. It’s our favorite Ugly Betty diva’s Christian-tinged performance of both “Mary Had a Baby” and “Go Tell it on the Mountain” on NBC’s 1993 Christmas special, David Foster’s Christmas Album. Of note: The fact that she looked nearly the same 15 years ago as she does today. She’s admitted to Botox in the past, but it’s rather uncanny. How can she be so fabulous?

But back to the performance… it’s rather demure and controlled at first, but don’t let that fool you. Watch it all the way through—at about the 3:40 mark, the gospel choir parades in to give back-up to Vanessa and it’s a blessedly joyful Christmas fandango from there on out!

PopWatchers: Do you remember this performance—or is it new to you? Is Vanessa—gasp!—lip-synching? Did this get you into the holiday spirit at all? (Of course it did!)
