Paris Hilton in a book store? MailOnline reports she was spotted Monday (Jan. 21) at WeHo’s Book Soup browsing the aisles with her boy toy, River Viiperi. MailOnline’s spy says she spent as much time doing her lips as moving her lips while reading. But its photos show the hotel heiress actually carting away two books. From the pic, it’s impossible to figure out the titles. But given that Paris is 31 and River only 21, we’re wondering if one of the books wasn’t by that other Paris (Ilona Paris, author of “Hot Cougar Sex.”)
