4. Chelsea Handler and Angelina Jolie

Handler, who is friends with Brad Pitt ex Jennifer Anniston says that a failed relationship has nothing to do with how she feels about Angelina Jolie. Calling her a “bad girl,” among other things, Handler has not tried to conceal how she feels about Pitt’s current squeeze. This one is a bit of a one-sided feud since Jolie has said very little about it.
