Kristen Bell
NBC's The Good Place actress married Dax Shepard at the Beverly Hills courthouse in a pair of black pants and a black top.
Kaley Cuoco
The Big Bang Theory actress looked gorgeous in her pink Vera Wang gown. The dress had a sweetheart neckline, a hand-gathering detailed bodice and hand appliqué Chantilly lace accents. The veil, also by Wang, was nude tulle with petal-pink floating hand appliqué Chantilly lace.
Alas, looking radiant on her big day wasn't a guarantee of happily ever after. Cuoco divorced Ryan Sweeting in September 2015.
Gwen Stefani
The hand-dipped pink wedding dress by John Galliano, then the head of Dior, that the singer wore to marry now ex-husband Gavin Rossdale in 2002 was an instant unconventional classic—and in 2011 it became a piece of history when it was acquired by London's Victoria and Albert Design Museum.
