Nicki Minaj's new beau is showing the world how serious he is about her.

Weeks after the pair made their relationship Instagram official the "Barbie Dreams" rapper and boyfriend Kenneth "Zoo" Petty have reached a new level of commitment. Minaj, 36, posted a video of her man's first and only tattoo: her birth name tattooed on the side of his neck.

"Did ya tat hurt zaddy? his first tat - frontin like it didn't sting #Onika #HeavyOnIt #SuperSleezy," she captioned the clip.

The tattoo comes after Minaj and Petty, who was recently revealed to be a registered sex offender in New York, spent her birthday together in New York City. The rapper shared a video of her and Petty dancing together during the celebration.

Minaj's relationship with the 40-year-old came as a surprise to fans. In addition to being a registered sex offender, accused of using a "knife/cutting instrument (e.g. ax, ice pick, screwdriver, switchblade, Kung Fu stars, cane sword, etc.)"  during an attempted rape, her boyfriend spent seven years in prison for the shooting death of a man named Lamont Robinson. He's been arrested about 12 times total, according to The Blast.

Minaj defended Petty after news broke saying, "TMZ, y'all can post these 'til ur blue in the face. No one on God's earth is perfect. Oh, I forgot - y'all have never sinned; nor have your loved ones. Heard you."
