UFC star Nina Nunes just gave birth 6 months ago ... but tells TMZ Sports she CAN'T WAIT to get back in the Octagon and fight on Saturday!
Nina -- formally known as Nina Ansaroff -- had a baby back in September with her longtime partner Amanda Nunes, who happens to be one of the greatest combat sports athletes of all time!
Nina ain't too shabby herself -- she's the #5 ranked UFC strawweight -- and she's taking on fellow mom Mackenzie Dern on "UFC on ABC 2" on April 10.
