Gloria was at the "So Sexy L.A." party at SKYBAR in West Hollywood Thursday night ... when our photog asked about her estranged hubby, 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.
