For years, Los Angeles paparazzi have made a living shooting celebs walking out of Starbucks while slurping down lattes from the chain's signature cups. Talk about free advertising! Now, however, we may be seeing a new degree of confluence between celebrity photojournalism and product promotion. Jennifer Aniston, who recently signed on as a spokeswoman for smarterwater, seems to be traveling with a bottle in view, just in case the paparazzi strike. (See the photo here, from the X17 agency.) As much as celebs complain about the paparazzi,they have always known how to make good use of them. Expect to see much more of this kind of unholy marketing.
