Ice-T RIPS CoCo Over Photos with Another Guy

Totally Fine with Ice-T: His hot wife taking half-naked, ass-bearing pics and posting them on Twitter.

NOT Fine with Ice-T: His hot wife taking fully-clothed pics, but with ANOTHER RAPPER!!!!

Ice-T is FURIOUS after pics of CoCo and rapper AP.9 surfaced on the internet Friday ... with the two looking pretty friendly in Vegas. Specifically they're seen dancing, hugging, cheek-kissing and holding each other ... like really, really, close.

Ice made his feelings crystal clear on Twitter, saying ... "Don't get it twisted, I'm not happy about this s**t."

He continued, "Most of [the pics] are disrespectful and in bad taste. She's made me look and feel like s**t. I say this on Twitter because there's no way to avoid the obvious misconduct of a married couple."

CoCo also tweeted about the incident when the pics first popped up saying ... "Please guys I'm happily married. Sometimes fans and friends take silly pics. It's harmless."

Ice seems to disagree.
