You may know a thing or two about US Presidents, but you won't believe how much 8-year-old expert AUSTIN SCHUSTER knows! He's got all sorts of presidential knowledge and will share it all with Ellen today. One thing Ellen knows is that NICOLE RICHIE just announced that she's marrying her boyfriend, Joel Madden! Ellen wants to get all the details from her, especially where the bachelorette party is. Nicole is known for her great style, and you can look just as good -- now that she's started her own fashion line, "Winter Kate." Then, it's been a wild year for BEN MCKENZIE. His show "Southland" almost got canceled, but it found a new home and it's better than ever! He'll also let Ellen know how his adorable dog Oscar is doing. Tonight also begins another week of "American Idol" -- and Ellen is getting ready!
