Is it true that Firestar's father is Pinestar?

Jake is a ginger cat and he seems interested in the forest and we know that Scourge's father was that. We don't know for sure but it just seems really likely.

--------------------------------------------------------------------------------------

We know that Scourge's father is Jake, and Erin Hunter revealed that Jake is Firestar's father also. Which means that Bluestar met one of their future leader's father when she was an apprentice. Which also means that Firestar killed his half-brother, Scourge, over a fight for the forest.
