Mom and Dad are finally getting out of the house! Nicki Minaj,38, and husband Kenneth Petty, 41, made a rare public appearance in Malibu on April 8, grabbing dinner at — where else? — the beloved celeb hotspot Nobu. The couple attempted to keep as low a profile as possible during their date night, with Nicki keeping her head down and shielding her face with a protective mask and oversized sunglasses.
