The couple exchanged vows at a private ceremony in Santa Barbara, CA.
Griffin and Foster were engaged last year.
Foster was previously married to TV and Broadway name Christian Borle (Peter and The Starcatcher, "Smash").
Griffin is a screenwriter and sometimes actor, best known for his writing credits which include "Ravenous," "Matchstick Men" and "Ocean's Eleven." Recently, he played a small role in "The Wolf of Wall Street."
Foster is a two-time Tony award winner for Anything Goes and Thoroughly Modern Millie. She will lead the cast of "Younger" on TV Land, currently in production, and described as being about a single mom who suddenly finds herself back in the workforce, whose unexpected biggest challenge will be her age in a land of twenty-somethings.
