Yes, you read that correctly: Rihanna and Anthony Bourdain will both be at Union Square tonight, albeit on opposite ends. And no, this isn’t a promotion for a “Disturbia”-themed food tasting convention. Here’s details on both separate events:

• Rihanna album signing @ Best Buy Union Square — 5 p Uninvited the download.m.
  Rihanna will be signing copies of her newly released album “Rated R,” which is getting pretty awesome reviews. You might need to get to Best Buy early (as in 8 a.m.) in order to secure a wristband for the event. For the large-foreheaded, Barbadian pop queen, it’s probably worth it.
• David Chang in Conversation with Anthony Bourdain @ Barnes & Noble Union Square — 7 p.m.
  Renowned chef David Chang is promoting and signing his new cookbook-memoir “Momofuku” with everybody’s favorite foodie Anthony Bourdain, the coolest guy to ever host a show about food. Oh yeah, renowned chef David Chang will be there.
