Learn more about Selena's outfit on David Letterman

Who: Selena Gomez

What: The Late Show with David Letterman

Wearing: Dress by Emilio Pucci

Selena Gomez went to the Ed Sullivan Theater yesterday for an appearance on Late Show With David Letterman. The singer, 18, was promoting her new single "Who Says" from her upcoming album, that nothing less will be their third album, sounding like a rock star in an elaborate mini dress Emilo Pucci and a scarp with a zipper detail. With a graphic print skirt, bodice adorned leather, and long-sleeved top, is a party dress if I ever saw one, but Gomez has a good reason to celebrate: in the morning, she confirmed her relationship with Justin Bieber.
