Funny... definitely. Talented... without a doubt. Devious, arrogant, precocious -- only on screen! JONAH HILL is here, joining Ellen to celebrate his Academy Award-nominated role in "The Wolf of Wall Street"! The actor earned his second Oscar nod this year for his incredible performance in Martin Scorsese's latest picture, playing a salesman with the goal of striking it big on Wall Street. The world has come to know Jonah as an entertainer who can wear the mask of many faces: a Klansman in "Django Unchained," an ambitious Yale grad with a knack for statistics in "Moneyball," and an embellished version of himself in "This Is the End." Ellen and Jonah both love improvisation; see what our host has in store when he takes the red seat! Then, LIONEL RICHIE performs one of his classic tracks, and it is guaranteed to be smooth, sensual and resonating "All Night Long." The pop/R&B crooner and Commodores legend has been courting audiences for decades with his love songs. He made it romantic to say "Hello," epitomized the charm of a Sunday morning, imagined "Dancing on the Ceiling," and went platinum over and over again with his many albums. Lionel truly can't slow down, and he's got a huge surprise waiting for Ellen and her fans when he returns! On Wednesday, Ellen goes from downtown to Motown!
