If you weren't already a Charlie Hunnam [1] fan, then his interview with Kristen Bell [2] will change your mind. And if you're already a fan? Good luck, because your heart is about to burst watching him talk about his 13-year-old heartbreak and the time he saved his cat. Kristen stepped in to host Jimmy Kimmel Live [3] on Thursday, and the actress asked Charlie about everything from his Sons of Anarchy [4] days to how he got into shape for his new movie, King Arthur [5]. (She also did a favor for fans everywhere by pointing out that, yes, he smells good.) The two of them have hilarious chemistry, so somebody definitely needs to cast them in a movie together ASAP, please and thank you.
