'Real Housewives' star Vicki Gunvalson isn't doing a damn thing to shut down the rumor that's become a big thing on the show ... that Tamra Judge 's husband, Eddie , might be gay.

The "OG from the OC" caught some heat this season when Tamra found out Vicki and other cast members were insinuating Eddie had made out with a man years ago. Vicki told us Tamra's got no one to blame but herself for this coming up on the show.
