Robin Williams, Selena Gomez

He hasn't been here in over three years -- the hilarious and talented ROBIN WILLIAMS is back in Ellen's studio! There's no telling what will happen when this wild and unpredictable comedy genius sits down with our host, but it's sure to have you in stitches! She's a beautiful young woman with an even more beautiful voice, SELENA GOMEZ is here to catch Ellen up on her life, career, and her larger than life boyfriend, Justin Bieber! Plus, her band The Scene is here, and together they're performing their hit song, "Love You Like a Love Song" from their CD, "When the Sun Goes Down." The sun is going to be shining bright on Ellen this Thursday!
