Do people really "promote" their book going to paperback?

My conspiracy theory is that Lala is doing all this press because the VPR spin-off rumors are true. I don't know *which* rumor is true, that she is getting her own spin-off or "Vanderpump Valley" is coming.

Anytime a reality tv personality is going on interviews, morning shows, podcasts, it's to promote SOMETHING, or get publicity for something. You all have informed me that she was "promoting" her book being released as a paperback copy. Do people REALLY go on press junkets to promote that? Is she that desperate to make the NYT Best Sellers list? Or do you think this is fishy like I do?
