Trina -- Nothing's Cooking in My Oven, Rapper Denies Pregnancy Report

Trina is NOT squeezing out a mini-Montana anytime soon -- as in, the rapper is NOT knocked up and expecting a baby with French Montana ... TMZ has learned.

Trina first heard she was "pregnant" with fellow rapper French's child when a story started circulating on the Internet today -- but Trina's rep Aleesha Carter tells us the 34-year-old rapper is 100% unpregnant.

Of course, it's biologically possible -- Trina and French are still dating banging -- but we're told neither's trying to make anything other than beats.
