Hilary Duff has made a true BFF on the set of her cable series “Younger.”

Not only does Molly Bernard play Duff’s bestie on the hit show, but she’s also godmother to her baby girl, Banks. And as if that wasn’t enough, Bernard revealed that she officiated Duff’s wedding to Matthew Koma in the front yard of their Los Angeles home Saturday.

The actress was joined by “Superbad” actor Christopher Mintz-Plasse and posted a photo of them in suits on Instagram, writing of their expressive faces, “@mintzplasse’s somber farewell to his better half @matthewkoma and my personal panic joy as we wed him to @hilaryduff.”

Bernard and Duff even changed into complementary sequin gowns to “boogie” to DJ Denise Love Hewett.
