According to Maggie Grace there was definitely cast bonding on the set of Breaking Dawn
From Contact Music:
The Twilight Saga: Breaking Dawn stars Casey Labow, Maggie Grace, Julia Jones and Mia Maestro have become best friends on and off the set – and they regularly hook up for coven-like dinner parties.
The foursome clicked on the set of the final Twilight movies – and now former Lost star Grace hopes they’ll be friends for life.
She says, “It was a gaggle of fun girls and we still have these coven reunions, as geeky as that sounds. We did little field trips during the shoot, and we still have dinner parties when we’re all in L.A.”
