Had NOTHING to do with race and NEVER would!!!" The Disney Channel star then posted a lengthy message on Instagram, saying in part, "There is a fine line between what is funny and disrespectful. Someone said something about my hair at the Oscars that left me in awe . . . because I was hit with ignorant slurs and pure disrespect.

Once news broke that Pitt and Jolie were divorcing, Handler ripped back into Jolie, saying: "There are rumors that part of the problem was that Brad was allegedly drinking and smoking too much weed," she said.
