Kourtney Kardashian's son Mason Disick really enjoys his aunt Kylie Jenner's birthday cake, and it's a mini-"Full House" reunion as Lori Loughlin (and her daughters) visit John Stamos on Broadway -- a glimpse of what Uncle Jesse and Becky's life may have looked like!
Plus, Dwayne "The Rock" Johnson shows off his huge guns with hottie Gina Carano, Lea Michele channels Britney on the "Glee" set, and David Arquette and a pooch put on their best mean faces.
