PARTY HOPPING: Friends of Dennis Hopper’s piled into his and Victoria Duffy’s Venice Beach compound on Friday night, not only for Hopper’s birthday bash (which he shared with the debut of conductor Esa Pekka-Salonen’s new work at the L.A. Philharmonic) but to get a gander at his amazing art collection, filled with Warhols, Basquiats, etc. The people-watching wasn’t bad either: Sean Penn, Steve Martin, Army Archerd, producer Art Linson, director Tony Scott, Mike Medavoy, Mitch Glazer and Kelly Lynch, Robbie Robertson, Colin Farrell, Selma Blair — and Daryl Hannah, who was wearing a Dolce & Gabbana leopard skirt as a strapless top over pants, a look that’s rearing its layered head again in L.A. this season. “I couldn’t figure out what else to do with this skirt!” said Hannah, who looked like she was revisiting her “Clan of the Cave Bear” days. But with all the stars and the art to look at, one thing every guest noticed: a “Waterworld” pinball machine that features both Kevin Costner’s and Hopper’s faces.
n FAMILY JEWELS: Visitors to London will soon be able to judge for themselves just how talented Britain’s royal family has been at collecting art. On Wednesday, as part of the Jubilee celebrations, Queen Elizabeth will open the revamped and enlarged Queen’s Gallery at Buckingham Palace, following a $30 million makeover by the architect John Simpson. The seven galleries in the Queen’s Gallery house five centuries of art reflecting the tastes of monarchs from Henry VIII to the present-day Queen. The 450 works include drawings by Michelangelo, Da Vinci and Holbein; paintings by Van Dyck, Vermeer, Reynolds and Gainsborough; a neoclassical sculpture by Canova, and a diamond diadem made for the coronation of George IV. The most recent addition to the collection is a controversial portrait of the Queen painted by Lucian Freud last year that depicts the monarch in a glum and unflattering light.”
