New York, Dec 19 : Playboy founder Hugh Hefner's new galpal Dasha Astafieva made heads turn when she arrived in a see-through mini dress at the red carpet event for Playboy's 55th anniversary.

The Ukranian-born Playmate was seen wearing just a thong underneath her dress, which she quickly got rid off, flashing her bottom to the thrilled paparazzi.

It''s unclear whether Astafieva is officially a new love interest for Hef - but the pair looked cozy, posing together after the thong-dropping episode.

Hefner, who is dating new girlfriends Crystal Harris and twins Kristina and Karissa Shannon - stars of the hit Bravo show "The Girls Next Door" -hinted that Dasha may too join his galpal's league.

When asked by E! Online whether Dasha will be a new member of his Playboy mansion, Hefner gave an almost positive reply.

"You think we''re gonna let her get away?," The New York Daily News quoted Hefner, as saying. (ANI)
