A few weeks ago, reports emerged about Cass possibly linking up with her new boyfriend courtesy of a trainer ex-boyfriend Diddy hired.

Here’s what we’re told. Diddy’s trainer, Jamal Liggin, got so busy he hired several trainers as backup, including Alex Fine. Diddy tagged Alex to train Cassie over the last year. As we reported, Diddy and Cassie broke up several months ago after a decade-long relationship, but our sources claim Cassie and Alex hooked up before the split. We’re told what especially galls Diddy … he paid Alex to train his then-girlfriend and feels betrayed. (TMZ)
