Two of Eclipse's newest stars, Bryce Dallas Howard (who's replacing Rachelle Lefevre) and Xavier Samuels stuck together Sunday for a stroll through Vancouver with Bryce's hot hubby Seth Gabel and son Theodore.

I know it's probably not her doing, but I just can't look at her all smiley and laughing in Vancouver knowing she stole the role out from under Rachelle, who was so amazing in the first film!

She better be brilliant in Eclipse or I won't be able to forgive Twilight producers for making this bizarre, mid-season switch!
