There's a war of words going on between Jennifer Aniston and Bill O'Reilly.

Aniston is going after the Fox News host after he criticized her for pushing single parenthood in her new movie, The Switch, in which Aniston plays a single woman who uses a sperm donor to become pregnant.

In promoting her movie, Aniston gave an interview saying, "Women are realizing it more and more...that they don't have to settle with a man just to have that child."

That prompted this response from O'Reilly:

"She's throwing a message out to 12-year-olds, and 13-year-olds, that hey, you don't need a guy, you don't need the dad...that's destructive to our society."

Now Aniston is fighting back. She tells People magazine:

"Many women dream of finding Prince Charming, but for those who've not yet found their Bill O'Reilly, I'm just glad science has provided a few other options."
