Another big break up for Kris Humphries … TMZ has learned the former Mr. Kardashian is separating with his high profile publicity team after 73 days of holy matrimony … exactly one day longer than his marriage.  Read more after the jump.

Sources tell us … Humphries and Anderson Group Public Relations have decided to end their professional relationship … due to a major disagreement over a long-term strategy for Kris’ off-the-court career.

The two sides first came together around the time Kim Kardashian pulled the plug on the marriage — after 72 days — and Kris felt he needed for some advice on how to handle his image through the tough times.

But after the crisis, Kris and AGPR simply did not see eye-to-eye on a post-Kim game plan. We’re told AGPR was unhappy with the outcome of Kris’ appearance on “Good Morning America” last month.

During the “GMA” appearance, Kris brushed off questions about Kim … and instead, focused on baking desserts during a cooking segment with his mother.

According to our sources, Kris has already taken on a new PR firm in NYC and wants to focus solely on basketball.

We’re told the relationship with AGPR ended on reasonably good terms … and both sides REALLY want to stay friends.

… like that ever works.
