Rihanna: 9 East 13th Street

[Submit your own Gawker Stalker sightings to stalker@gawker.com] July 25th @ night My friends and I sang karaoke with Rihanna herself at Shanghai Square. She showed up wearing a really fierce red ensemble, with a giant entourage in tow.

She sang "Livin' on a Prayer" and "Before He Cheats." Ironic.
