Kristen Bell [1] and Dax Shepard stopped by The Ellen DeGeneres Show [2] on Friday to celebrate the host's 60th birthday [3]. (Unreal, we know.) But the adorable couple [4] found themselves in a little gift-giving competition after Dax serenaded Ellen [5] with an original song he wrote about how "sexy" she is. Kristen, not one to be outdone, later came to the couch and brought a gift of her own that recognized Ellen's most beautiful feature: her heart. Cue the awws. Watch both videos above and below.
