Two of the most beautiful women in the world, JENNIFER LOPEZ and CAMERON DIAZ are here! They star in the film "What to Expect When You're Expecting," and we can expect a show you won't soon forget! From judging on "Idol" to being one of "Charlie's Angels," there's little these two haven't done, and the only place you'll see them together is right here on Ellen! Then, another television exclusive! JOHN MAYER underwent vocal chord surgery, and he's sitting down exclusively with Ellen to tell her about his recovery. He's also talking about his album, "Born and Raised," and the feelings that inspired it. Plus, teen queen VICTORIA JUSTICE is here! The star of Nickelodeon's "Victorious" will perform a song from her album, "Make It in America." It's all happening this Friday!
