Last week on "The Office," JOHN KRASINSKI said goodbye to his friend and co-star, Steve Carell. Today John will tell Ellen all about life after Steve -- and Ellen will try to find out who the new boss will be! That's not all that's new with John... i... (more)t's been less than a year since he married Emily Blunt, and Ellen will hear all about it from the newlywed. A lot of audience members have braved Know or Go, but only a few have stayed long enough to make their mark! Today Ellen brings back three of the best for the ultimate Know or Go All-Stars Round! Last week, Ellen went to her home away from home -- Las Vegas! She brought along some cameras when she visited the luxurious Venetian and Palazzo Hotels, and will show you everything that happened when she decided to crash a bachelorette party!
