Nikki Bella, 35, looked absolutely gorgeous last night in a off-the-shoulder white lace sheer crop top, high-waisted yellow pants, and a mustard and silver bag. She wore her brunette hair straight and down, and had on a simple delicate necklace and dangling earrings. Nikki rocked neutral makeup for the Variety Children’s Charity Poker and Casino Night event, and was joined by newly-official boyfriend, Artem Chigvintsev, 37.Artem looked amazing by Nikki’s side and they posed for pics on the red carpet together at the event. He wore a black blouse that was unbuttoned at the top. Artem wore dark blue pants and a black and gold belt, as well as shiny black dress shoes. He rocked a scruffy look and his blue eyes popped with his ensemble.Around a week ago, Nikki opened up about her relationship with Artem and how they had been casually dating for months before becoming official together. “I pushed Artem away because I wasn’t ready for anything,” the famous reality star said on The Bellas Podcast. “What was coming at me with Artem, this amazing guy, he makes me laugh, it’s easy to be around him, he makes me feel stress-free.
