Russian research?

IVANA Trump is more than a handful. During designer Dennis Basso’s recent presentation, she seemed more interested in Russianspy-turned-fashion-blogger Aliia Roza’s cleavage than the clothes. A source said that Ivana made her way to where Roza was standing near the bar at upscale Mediterranean restaurant Limani when she allegedly “asked her if she could feel her boobs.” “Sticking her hand down her blouse, she goes, ‘This is not sexual. It’s research,’ ” the shocked witness recounted, noting that Roza was dressed in a low-cut black top. Roza — whose site lists her as a TV host, producer, blogger and “philanthropist investor” — later told us that she was able to laugh it off. “Ivana was so funny,” she told us when reached for comment. “She was lovely and really sweet.” The ex-spy has said she fled Russia after falling for a target she was tasked with seducing. Ivana did not get back to us.
