Keltie Knight is gearing up for her next era, and while it, of course, includes the "LadyGang" podcast, there's also a book involved. "I'm getting even more unhinged, if you can believe it," Knight, 43, told Us Weekly exclusively at the "LadyGang" podcast's LadyWorld festival in Miramar Beach, Florida, this past weekend. "I am writing a solo book. It is called The F*** Them Theory: Self-Help for People Who Are Done Being a Bigger Person. My manuscript is due next week, so no stress." Knight went on to tell Us the inspiration behind the book and its showstopping title.
