This year keeps getting better and better for Nicki Minaj. Today the rapper retweeted Joan Rivers and revealed that she is going to appear on Joan's show, 'Fashion Police'. The tweet was a twitpic of the Young Money mistress and the fashion show host posing happily together. Just recently Nicki's debut album Pink Friday reached platinum status, so appearing on the E! channel show is only going to add to those sales. Check for Nicki's appearance tomorrow at 10:30pm est.
