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."
