Apparently, Dax Shepard wasn't kidding when he said that he's a huge fan of Brad Pitt . Earlier this week, Dax stopped by The Ellen DeGeneres Show, where he revealed that he has a not-so-secret obsession with Brad and nearly had a heart attack  when Ellen gifted him with a giant portrait of him with Brad. Dax's excitement about the portrait was completely genuine, as Kristen Bell  explained when she dropped by Ellen's show for a segment that will air today. As Kristen tells it, Dax already gave the picture a special place in their home. Watch her interview above.
