Kim Zolciak was certainly havin' fun filming her reality show amid her divorce from Kroy Biermann ... hitting it off with Chet Hanks during production in Colombia.
Multiple sources connected to the show tell TMZ ... Kim and Tom Hanks' son were acting flirty toward each other while cameras were rolling in Medellín for MTV's "The Surreal Life."
We're told they really hit things off, with others in the house thinking they might've caught feelings for each other during the 2 weeks of production .
