Naomi Campbell and her billionaire ex, Vladimir Doronin, had yet another awkward near run-in at the Interview magazine party at soon-to-open restaurant Monarch on Tuesday night.

After the supermodel — looking stunning in Versace — celebrated US Open runner-up Novak Djokovic at his foundation gala event at Capitale, spies said Campbell, who we revealed broke up with Doronin in May, arrived at Monarch for the Interview bash at about 12:45 a.m. She was then brought to a VIP table located just a few paces away from Doronin.

“Only a security guard separated them,” said a source.

Campbell didn’t seem fazed by his presence, but he was out like a shot.

“She went in, and he came right out,” said a witness.

Interview’s Fabien Baron and Karl Templer celebrated their latest issue featuring seven supermodels on its cover with Amber Valletta, Chanel Iman and boyfriend A$AP Rocky, Karlie Kloss, Leonardo DiCaprio, Toni Garrn, Joan Smalls, Lindsay Ellingson, Doutzen Kroes, Liu Wen and Jourdan Dunn.

A source close to Vlad told us he is a friend of the owner of Interview and Vlad himself owns Interview in Russia and Germany. The source added, “Vlad was tired from traveling and was already planning on leaving. It was not a big deal at all and he didn’t even see Naomi.”
