A Ukrainian model and popstar (she sings in pop group NikitA), Dasha was crowned Playboy's Playmate of the Month for January 2009, and rocked up to the magazine's 55th anniversary playmate celebration on Hef's arm, sparking speculation that she was one of his new harem.
Dasha is the first serious girlfriend prospect we've heard of since he was spotted pashing 19-year-old trashy twins Karissa and Kristina Shannon. Do we consider this an upgrade?
Wonder what attracted her to Hef? In a recent interview she reckons she isn't into rich guys.
When asked how a man could do to impress her, she said "what not to do is to think offering me money or a life of luxury is the key to my heart.
"I’m a very independent woman, freedom is very important, so just because you have money doesn’t mean anything to me. I don’t like show-offs who boast about themselves. I love shy men, humble men. I am still waiting for my prince, but I find American men very interesting."
Guess Hef falls into that 'interesting' category!
Hef's ex Bridget Marquardt, who was also at the party, revealed that Dasha was selected for the magazine by none other than Hef's ex-main girlfriend Holly Madison. Bet she'd be fuming that Dasha has now won a place in Hef's 'heart'!
