LOS ANGELES — [Fox News] Her name is (literally) synonymous with such high-class publications as Harper’s Bazaar and Esquire, but Hearst Publications heiress Lydia Hearst is revealing a lot more than just her name to the world.

The 23-year-old model/handbag designer/socialite stars in the upcoming bittersweet romantic comedy “Frost,” playing provocative party girl Stella.

The film premieres in the Big Apple next week as part of the Gen Art Film Festival; tickets for the premiere already have sold out; however, Tarts has been told that Hearst does, indeed, take her top off in a nightclub scene in front of a full house. But that obviously wasn’t a bother for the waif-like beauty.

“Lydia didn’t have any hang-ups on the set; she is clearly confident with her own body and relished the provocative nature of the role,” producer Mike Landry said. “She just has this sexy radiance — most men would give their right arm for the chance to go out with her, and I’m sure many women are jealous of her and she seemed to enjoy the playfully sadistic side of Stella.”
