Ellen's favorite duo is flying in from England, flaunting their smiles at the Kid's Choice Awards, then coming to visit our host, dressed to impress as always… SOPHIA GRACE & ROSIE are here! There can never be enough giggles, ruffles and sweets to go around. The adorable twosome and their bubbly stories will be overflowing once again! Plus, with new siblings on the way, these soon-to-be big sisters have lots of planning to do. It's tea for three when Sophia Grace & Rosie return! Then, SIMON BAKER is here! "The Mentalist" returns with updates from season six of his hit CBS series, but don't worry, no spoilers! Simon will offer insight on the new direction of his character, and hopefully give details on that brown cowboy hat he was spotted toting around on the set. The actor brings exciting news from on and off the screen to share with Ellen! Flying high from a world ruled by superheroes, "Captain America: The Winter Soldier" star ANTHONY MACKIE stops by! The actor makes his first appearance on the show as he rises in the Hollywood spotlight. Anthony has rapped poetry as Tupac Shakur in "Notorious," fought for freedom as a soldier at war in "The Hurt Locker," and took on the life of a criminal in "Pain & Gain." Next up, he plays a comic book hero… and he’s swinging by to introduce himself to Ellen! On Wednesday, Ellen's exploding with character!
