Shannen Doherty and Tori Spelling are opening up about the tougher moments in their friendship.

Spelling recently stopped by Doherty's "Let's Be Clear" podcast, during which the two reminisced about some of their wild times together going out in Hollywood and all the laughs they share, before transitioning to what led to the break-up of their friendship.

The two revealed they had caught up on a recent flight back from Pittsburgh, during which they "were trying to figure out" what "pivotal moment" ended their friendship.
