The actor's costars Candace Cameron Bure, John Stamos, Bob Saget and Kimmy Gibbler herself, Andrea Barber, were all on hand for the ceremony, sharing photos on Instagram all day leading up to the "I Dos." Series' creator Jeff Franklin was also in attendance.
Noticeably absent were Mary-Kate and Ashley Olsen, Lori Loughlin and Jodie Sweetin.
A rep for Loughlin tells toofabthat the actress had a pre-planned vacation with her family and couldn't make it -- but she did send her congratulations via Twitter.
As for Sweetin, she tells us "I was totally invited! I wish I could be there, but with kids and work, I wasn't able to get away for it. If it was in town, I ABSOLUTELY would've been there! I'm really sad I'm missing it."
So far, no response from the Olsens.
We love that this group has remained so tight all these years and were able to celebrate this special moment in Coulier's life together.
