Larry David came to the defense of 'The Bachelorette' star Ashley Hebert on 'The Tonight Show With Jay Leno.'

Butting-in on Leno's interview with Hebert every chance he got, the 'Curb Your Enthusiasm' star expressed an extreme dislike for Bentley Williams, who Hebert says broke her heart.

"I'm gonna kill that mofo," David said.

"I don't know what this guy did did, but I really dislike him," David added.

Hebert said that she was blindsided by what happened with Bentley, but will she go out with him again? Not if Larry David has anything to say about it!
