Gloria was talking to our photog in West Hollywood about her estranged husband, Clippers star Matt Barnes ... and his very public hatred of Kaepernick.
Just a few weeks ago, Barnes called Kaep "a hoe" on Instagram -- which is why our guy asked Gloria if she knew what was behind the beef.
Watch ... Gloria took the ball and ran, first telling us -- "There's been a bunch of different rumors" about her and Colin hooking up. But she says, "I've never had a thing with Colin Kaepernick."
Double G seems to think fans blame her for their feud, but she tells us it's something else altogether.
