SEEN & HEARD

So it wasn't all on one side. British tabloids reported last week that Oliver Hoare, the London art dealer PRINCESS DI supposedly phone-pestered last year, is now obsessively calling her. "Longing to hear you and love you madly," was one of the messages Hoare allegedly left for Di with an answering service. Meantime, Hoare's chauffeur asserted that the couple has trysted in the homes of friends since 1991.

Volatile alterna-goddess COURTNEY LOVE has found a new outlet for all of her raw emotion. The widow of Kurt Cobain and lead singer of the ever more successful rock band Hole will make her film debut opposite surfer dude-action hero-Hamlet Keanu Reeves in the dark comedy Feeling Minnesota.

Back with the Boss for an E Street Block Party

When BRUCE SPRINGSTEEN went searching for a new sound a few years ago, he dismissed his celebrated E Street Band, which had played on the records that made him a superstar. That left some bitter feelings, but the E Streeters-including the band's most notable member, saxophonist CLARENCE CLEMONS-resurfaced last week to perform with Springsteen before an audience for the first time in seven years. The purpose of the show was to film a video for one of the four new songs that have been added to Springsteen's greatest-hits collection. The mood was convivial. After hours of filming, Springsteen shouted, "The heck with the video!" and he and the band joyfully launched into their old hit Cadillac Ranch.

AMO, AMAS, AMATO

It was one week after Valentine's Day, but the spirit of the occasion was still happily reverberating for New York's Republican Senator ALFONSE D'AMATO. He called a press conference at a Manhattan restaurant not to discuss Whitewater or debate the balanced-budget amendment but to gush and blush, tell the world that he is in love and even sing a few bars of It's a Sin to Tell a Lie. The object of his affection is CLAUDIA COHEN, the multimillionairess ex-wife of Revlon chairman Ron Perelman and the current gossip correspondent for TV's Live with Regis and Kathy Lee. "I feel like the frog who has been kissed by the princess," said D'Amato. "I think of Claudia as my Cinderella." The couple plans to wed once he is divorced from his wife Penelope, a community-college math teacher.

An End to His Troubles

Frasier star KELSEY GRAMMER can now add sex scandal to the list of personal upheavals he can put behind him. Arrested in the past for drunk driving and cocaine possession, TV's favorite therapist was vindicated of accusations that he had had a sexual affair with his daughter's 15-year-old baby sitter. Following a widely publicized investigation, in which the evidence included phone messages left by Grammer on the girl's voice-mail system, a New Jersey grand jury decided not to charge him with sex abuse. Grammer declared in a statement, "I have said from the outset that there was no basis for the allegations made against me."
