Despite their differences over the years, NeNe Leakes is letting her former 'RHOA' costar Kim Zolciak know she's got a friend in her -- especially during her divorce.
We got NeNe at LAX this week ... and she revealed to us that she and Kim ran into each other not that long ago -- noting KZ briefly mentioned she was having a hard time lately as it pertains to uncoupling with Kroy Biermann.
Check it out ... NNL says didn't elaborate on the statement .... and they kept the rest of their catch-up positive. Good to hear, considering how much they've beefed in the past.
KZ & KB have been at each other's throats for months -- we broke the story ... police were called to their home in Nov following a nasty fight between them and body cam footage shows Kroy blaming Kim for their financial struggles while also accusing her of "f***ing other men."
