Isn’t there some sort of rule that celebs have to acknowledge each other’s celebtastic presence when out and about? Maybe exchange winged trophies or something? Anything that acknowledges “I am fabulous in a very rare way and so are you.” Unless, of course, they’re in a tiff, or used to date the same girl, or their agents used to date and it didn’t end well so they’ve got to shun each other. But all those possibilites aside, does anyone find it sorta strange that Joe Jonas and Shia LaBeouf passed each other yesterday outside of Cafe Med in West Hollywood, and didn’t acknowledge each other’s famous selves in any way?

Really, there’s no reason to believe Joe and Shia have ever even met each other. But isn’t being a twenty-something star reason enough to at least crack a smile in the other dude’s direction?
