Jessica Lowndes Left PSR?, Why?

It's being said that Jessica Lowndes has left PSR but not by being dropped, but on her own. Question is why? Sources say for the longest she has been thinking about leaving for a while but no one ever knew why. It Sure as hell Isn't due to not being marketed enough since she is all over, maybe its a personal issue or maybe she has been with someone on the low. Who knows, but it still isn't actually confirmed, right now its in rumor status, we'll dig a little more to get the real answer.
