Things I know nothing about

From this week's covers of US, OK, People, Life & Style:

Kourtney Kadashian's pregnancy
Tom vs. Kate and Suri
Fergie and Josh
Khloe's baby
Rob & Kristen
Jessica defends Ashlee
Rihanna breaks her silence
Sarah Michelle Gellar
Michael Buble tells all
Tim McGraw
Kim Zolciak

These folks must be important, but I live in total ignorance.....
