What's On: Lululemon, Anthony Weiner and 4 CEOs

Here's what's up on Friday's Squawk on the Street:

--Numbers from Lululemon. This company has a very unique dilemma on its hands. It can't keep it's ultra-popular clothing on the shelves. So do they make clothes faster in China with less quality? Or do they keep the same supply chain and fail to meet consumer demand?

--Also on our list: the CEO of BlackRock, Larry Fink. We'll talk with the CEO of NYSE EuroNext, Duncan Niederauer. Then the CEO of Multi-Fineline Electronix. And the CEO of Nalco. It's a four CEO Friday.

--We're also debating whether Twitter's bad for the United States of America. Anthony Weiner made some big mistakes going from tweets to tears. If corporate America adopts the new form of communications, like they have other social networking sites, is it a good thing or a bad thing? Share your opinion.
