Brody Jenner is a single man after splitting from Josie Canseco, and we know what you're thinking, but ... no, the breakup has nothing to do with his freshly single ex, Kaitlynn Carter.
Sources close to the situation tell TMZ ... Brody and Josie are telling friends they've broken up, and one of their main issues was their age difference -- Brody is 36 and Josie is 22. We're told they're just on different pages in life.
The timing is interesting ... as we first reported, Miley Cyrus ended things with Kaitlynn a few weeks ago.
