Yesterday at the Oscars, Kristin Chenoweth performed a little musical number with Seth MacFarlane, but her gown at the Vanity Fair party afterwards was the real showstopper!  Chenoweth donned a strapless black Giorgio Armani gown with a peekaboo wrap in the back exposing a train of pale pink silk.  With a sophisticated ponytail, a Normal Silverman necklace, and a Christian Louboutin cluth, she had us singing high notes, too!
