It's the adorable MARIO LOPEZ! The charming host of "Extra" is dropping by to catch up with Ellen about his life, his baby, and his new underwear line! Whether she's dunking him in the dunk tank or challenging him to a game of Twister Hoopla, Ellen always makes the most of it when Mario's around. And, "The Bachelor's" BEN FLAJNIK is here! Ellen has been watching all season and she has a lot of big questions for him! She'll be sure to get some hints on which of the ladies may have won his heart. Then, the incredible singing duo that blew Ellen away is back! EMILY LUTHER and CHARLIE PUTH captured America's attention with their haunting performance of Adele's "Someone Like You," and now they're returning to the show that put them on the map to premiere their original song, "Break Again."
