Another new song from Lady GaGa's forthcoming mini album "The Fame Monster" has been unveiled. During the 30th anniversary gala for the Museum of Contemporary Art in Los Angeles on November 14, she showcased a track called "Speechless".

"[It] was this plea to my father [to get open heart surgery]. I sent it to him," she said of the song. "I have a lot of fans who are really lovely, young, troubled fans, but I want to remind them that you only get one set of parents."

Applying Japanese Geisha-style black lipstick, she was joined on-stage by Italian artist Francesco Vezzoli, who performed an art piece, and dancers from Russia's Bolshoi Ballet. Francesco donned all-black costume with a matching mask, while Lady GaGa and the dancers wore outfits from Muccia Prada and Baz Luhrmann.

Later that night, the costumes, including Lady GaGa's Frank Gehry-designed hat, were auctioned online. The pink piano which is decorated by artist Damien Hirst and was used for her performance was also sold at the end of the show.

Those who came to the event included Gwen Stefani and her husband Gavin Rossdale, Ciara, John Legend, Pharrell Williams, Madonna's ex-husband Guy Ritchie and Kate Bosworth.
