Executive producer Brian Peterson tells me he’s “very optimistic” the actress — who’s in the thick of contract talks as we speak — will be bringing Chloe back next fall for the show’s 10th season.

Asked whether it’s essentially a done deal (which is what I’m hearing), Peterson says, “We’ve learned the hard way not to say [it’s official] until everything is signed and dotted. So the best we can say is we’re really optimistic. And so is Allison.”

Translation: Chillax. She’s returning.
