Fan does the ‘Hiddle’ diddle

TOM Hiddleston got an orgasmic ovation for his new Broadway show: An audience member at “Betrayal” — in which “The Avengers” actor is currently starring — was moved to tears, moans and spasms of ecstasy on Wednesday at the Bernard B. Jacobs Theatre, reports The Post’s Johnny Oleksinski. A commenter on the All That Chat message board revealed that a person in their row at the performance, a well-dressed “young woman in her thirties,” felt the Harold Pinter play deeply — and she wasn’t Loki about it. “My companion could feel a rhythmic banging against his armrest, punctuated by occasional low moans and giggles,” the unwitting voyeur said. “[It] got faster and faster until there was one slightly louder ‘Ha,’ and she resumed her normal seat position, put her head back and closed her eyes.” Close to the sexy infidelity drama’s climax — when Hiddleston walks downstage and passionately kisses co-star Zawe Ashton — the panting woman kicked off Round 2, again adjusting in her seat, furiously pounding her armrest, letting out a ‘Ha’ and dozing off. “Betrayal” was good for her — she enthusiastically applauded at the end, and quickly exited, perhaps to light a cigarette. Still catching his breath, show spokesman Rick Miramontez had no comment. “The show was really wonderful and the cast first rate,” added the poster, who said this is the strangest behavior they’ve seen in 55 years of theater-going. “But you might want to avoid seat B-3.” The show is Hiddleston’s Broadway debut after previously running in London.
