Dax Shepard's been pretty open about his marriage with Kristen Bell in the past, and he took it a step further on Tuesday when he spoke openly about his relationship with his ex Briegh Morrison -- when she was right behind him!

Dax Shepard interviewed one of his longtime loves, Briegh Morrison, and the two got deep into their relationship, their breakup, and what comes after a breakup.

Morrison agreed that the breakup was particularly difficult, especially because she thought she and Shepard would go the distance after several years of dating and planning out their lives together.
