TRIBUTE TIME: Spotted in Rick Owens front row on Friday, Usher, who joined dozens of artists in paying tribute to Michael Jackson Thursday night, said he was still reeling from the shock. "It's a great loss. I've taken it very, very hard," the singer said. "We worked a lot together, we actually performed together one time. We've seen each other a lot over the years." Of Jackson's contribution to both the worlds of music and fashion, he said: "It would have been so much more."
