Lupita Nyong'o brought her infectious smile and personality to Ellen DeGeneres's post-Oscars show today. The newly crowed Academy Award winner joined Ellen to chat about the incredible night and, of course, being a part of the record-breaking selfie that took down Twitter. Lupita joked about being upstaged by her little brother, Peter "Junior" Nyong'o, who seized the opportunity to jump right in front of his own sister and Angelina Jolie to get in the picture. Lupita thinks the college freshman probably has show business in his future, and he's clearly not afraid to steal a spotlight! Ellen also got to the bottom of Lupita's friendship with Liza Minnelli and crowed Miss Nyong'o with her latest stylish headpiece. Watch now!
