'Love & Hip Hop' Star -- Nicki Minaj Was Right ... I SUCK!!!

Nicki Minaj BLASTED "Love & Hip Hop" star Kirk Frost for being a womanizing a-hole on national TV, and Kirk tells TMZ she was totally right to do so.

A recent episode of "LHH: ATL" aired showing Kirk cheating on his wife Rasheeda with TWO other women in a hot tub. FYI -- Rasheeda is 7 months pregnant.

Nicki ( a HUGE "LHH" fan) was pissed by the public display of douche-baggery and took to Twitter, writing, "Damn my n***a, after 15 yrs u wld embarrass the mother of your child while she's pregnant on nat'l tv like that? cornballs on deck."

She added, "And I dare u to say it ain't none of my business. U done sold it to vh1. It's everybody business."

But rather than try and make excuses, Kirk tells TMZ he knows he acted like a terrible person, telling us, "Nicki Minaj is a woman and she was speaking about me doing inappropriate things. I can't fault her for that. Every woman in America who watched felt the way Nicki did."

Kirk adds, "Not only was doing it on the show inappropriate ... but it was inappropriate period. And I hurt my wife."
