Madonna and Beyonce on Oprah's last show? I think I may explode into a big burst of rainbow:). From the shots I've seen, it looks Bey will be performing as well. Madge and the Big O have come a long way from when Madonna dissed her in Truth Or Dare. But I guess at some point even Madonna had to bow to the merciless power of Oprah. And she is working that 30's music star glam look. Okay, enough stan talk. View a few pics below.
