Usher USHERCAP041608_01.jpg We've got a couple thousand questions we'd love to ask either Usher or Jay-Z - but it looks like neither one of them's talking!

Last night, we caught the twin titans of modern music leaving Katsuya after a boys' night out. The paps pleaded with 'em both for a comment, but neither Usher nor the Jiggaman could be bothered to respond. Aw, c'mon - we just want to know what's up with your ring, Jay!
