In the saga of the on again, off again relationship between Jennifer Aniston and John Mayer, we must report that once again the couple have split.  Word in the celebrity world is that the breakup occurred when Aniston returned to L.A. after her European tour to promote Marley & Me.   Check out Jen eating dog food on German television.

People magazine indicates that prior to heading to Paris, Rome, London and Dusseldorf with her co-star Owen Wilson and his lady love Kate Hudson, Jen was spending more time with pals Courteney Cox Arquette and yoga instructor Mandy Ingber and less with Mayer.

The couple’s last breakup was in August 2008.  At that time, Mayer said, “I ended a relationship to be alone because I don’t want to waste somebody’s time if something’s not right.”
