They're one of the most adored "couples" in the movies, and they're great friends in real life, too! Celebrating their next onscreen romance, ADAM SANDLER and DREW BARRYMORE are here! The talented pair have dated, wed, and fallen in love over and over in films like "50 First Dates" and "The Wedding Singer," and now they're rekindling their fire in the new movie "Blended." Adam and Drew will spill their secrets to Ellen! Plus, Drew's got baby news, as she just gave birth to her second child! Then, the rest of the "Blended" cast comes to the party! That means KEVIN NEALON, TERRY CREWS, and WENDI McLENDON-COVEY drop in to make it five times the funny! Kevin's an Ellen all-star, regularly here doing funny bits for the show. Add to that Wendi, who starred in one of Ellen's favorite movies, "Bridesmaids," and Terry, who helped make "Brooklyn Nine-Nine" a TV hit, plus Adam and Drew… and the hilarity will be spilling out in all directions! After the big screen's favorite twosome chats, Ellen's delightful duo takes over! SOPHIA GRACE & ROSIE are back with more treats for everyone! This time around, they're doing it big for the kids, and it will be a surprise you'd never expect! Their shenanigans continue with Ellen! Plus, in an exclusive performance, SIA will step onstage to sing her hit song "Chandelier"! Though she rarely makes appearances on television (not even in her new music video!), the Australian pop singer is making an exception for Ellen, and it's guaranteed to be spectacular! Sia has worked with everyone from Jennifer Lopez to Lea Michele to Beyoncé, and her solo work is just as phenomenal. All eyes will be watching the musician's every move when she makes her debut on the show! Get ready to "Clap Your Hands"! On Monday, Ellen's got a full house!
