Flying higher than ever, LADY GAGA always dons the spectacular when she makes an entrance, and she will be taking it to a whole new level when she hits Ellen's stage again! The pop ingenue and superstar is here to bring the fab, and to give Ellen details on her latest, chart-topping album, "ARTPOP." After releasing hit records like "The Fame," "The Fame Monster" and "Born this Way," as well as internationally acclaimed tracks such as "Paparazzi" and "Just Dance," Gaga continues to beguile audiences around the globe with her work and distinctive, out-of-this-world style. In fact, she's so extraordinary, she will soon be performing in outer space! But first, she will rock, roll, (perhaps even soar!) as she takes over Ellen's dance floor, raising the energy with her famed moves and not-so-Poker Face. Need more?! See what she lets Ellen in on today and the extra special surprises she has in store for the audience! Note: no confirmation yet on whether she will enter by foot or magical device. From the otherworldly to a world scholar, 5-year-old solar system expert MARSHALL KIMBER returns to give Ellen another lesson on the depths of the universe. He's here and he's ready to educate… and to just sit there looking especially adorable. Check out his latest take on planets and stars, and his fashionable choice in kidswear. Maybe he'll even sing about the majesty that is Jupiter again! This Monday, Ellen goes Gaga!
