Nicki proceeded to upload a behind-the-scenes selfie, this time revealing the date of the shoot – August 15, just a month and a half before she gave birth.

She and her husband Kenneth Petty welcomed their 𝚋𝚊𝚋𝚢 boy on September 30 but have yet to publicly disclose his name or post a picture of his face.

The Anaconda hitmaker married Kenneth near the end of last year and announced that she was pregnant on Instagram this July.

Ten days before Halloween 2019, Nicki announced on Instagram that she was married to Kenneth, who goes by the nickname ‘Zoo.’

During their whirlwind romance Nicki included him in the lyrics to her single Megatron: ‘I f*** him like I miss him. He just came out of prison.’

Kenneth spent seven years behind bars for first degree manslaughter, which he pleaded guilty to after being charged with second degree murder, TMZ reported.

Citing insiders in law enforcement, the website claimed that Kenneth shot one Lamont Robinson three times on a street corner in Queens in April 2002.

Kenneth and some associates allegedly drove to a point across the street from Lamont, whereupon Kenneth emerged from the vehicle and walked over to his victim before firing into his stomach.

Lamont identified a photograph of his 𝓀𝒾𝓁𝓁er to police before dying in the hospital shortly after being shot, per court documents.

An investigator dismissed the reason for the shooting as ‘bulls***’ to TMZ, whose sources theorized that the violence was gang-related.

Kenneth, 42, earned his 𝓈ℯ𝓍 offender status after being convicted in 1995 of the first degree attempted rape of a 16-year-old girl.

He made use of a ‘knife/cutting instrument’ during the crime, according to public records from the New York Division Of Criminal Justice Services.
