On Saturday night in Los Angeles, Lady Gaga brought her music and sense of style to the art world when she performed at the Los Angeles Museum of Contemporary Art's 30th Anniversary gala. The singer performed the ballad "Speechless," from her forthcoming album The Fame Monster, side by side with dancers from Russia's Bolshoi Ballet.

Other A-listers on hand to celebrate the museum's anniversary included Brad Pitt and Angelina Jolie, Gwen Stefani and Gavin Rossdale, James Franco, and Jessica Biel. According The Wall Street Journal, Gaga played a piano designed by artist Damien Hirst while the dancers wore outfits designed by architect Frank Gehry, fashion designer Miuccia Prada and filmmaker Baz Luhrmann. The performance art piece was conceived by artist Francesco Vezzoli. Gaga wore a silvery gray ball gown with what appeared to be a papier-mâché headpiece.

"To have all of these very amazing art lovers — a very high-brow art community — to be engaged in the commercial community and blend the two together ... having my fans watch the video and be exposed to a level of art and a level of install that they may have never seen before, it's so beautiful," Gaga said about being part of the star-studded event.

Speaking to the press with her friend and photographer David LaChapelle at her side, Gaga continued, "The true mark of collaboration is a genuine union and a back and forth and a trajectory and something that's symbiotic," she explained. "And that's what happens when you don't stifle the creativity of others. That's when the lie becomes the truth."
