The "So Undercover" star was anything but at the 2011 pre-Grammy Gala and Salute to Industry Icons at the Beverly Hilton Hotel on Saturday in a dress that left little to the imagination.
Cyrus' pink dress included a mesh window that showcased what appeared to be the 18-year-old singer's bra-less chest, while "Undercover" co-star Kelly Osbourne's lace black dress with a sheer top showed off her black bra.
Ahead of the Grammy Awards 2011, Miley Cyrus and Kelly Osbourne attend the 2011 Pre-GRAMMY Gala and Salute To Industry Icons Honoring.
While the lower portion of Osbourne's dress was opaque, Cyrus' dress also showcased some mesh material around her thighs, though an opaque material down the center kept her entire body from being on full display.
Cyrus sat with Osbourne and her mother, Sharon, at the party and posed for photographs with Ciara.
"Reunited and it feels so good I missed my Miley!!!!" Osbourne tweeted.
Though she is not nominated for any awards, Cyrus will be attending the 53rd Annual Grammy Awards Sunday night and can't wait to see Christina Aguilera perform during the Aretha Franklin tribute.
"I stopped by and I saw a tiny part of Christina's rehearsal," she told MTV.com. "She's a good friend of mine and it was amazing. I can't wait to see her perform."
The Grammy Awards air Sunday night at 8 p.m. on CBS.
