Kristen Bell wore a black designer gown to the Grammy Awards Sunday night, but all eyes were on her left ring finger, where she debuted a diamond ring from comedian Dax Shepard.

Shepard proposed over the holidays, but the couple just went public with the news Sunday.

The actors appear together in the new romantic comedy When In Rome — although not as a couple.
