How does Miley Cyrus give back? By exposing her breasts at a charity function! The wild girl was scantily clad in a bondage-inspired Tom Ford dress at the 2014 amfAR LA Inspiration Gala.

The event, which raises money for AIDS research, was held at Milk Studios in Hollywood. Despite her sexed-up, boob-baring ensemble, Miley's date was none other than Trish "The Dish" Cyrus, her mother.

After the "Wrecking Ball" songstress' performance, the singer and her boobs cozied up with Rihanna, whose tatas gave Miley's exposed funbags a run for their money, and one of the night's honorees, Tom Ford.

We hope Miley's lady lumps had a blast last night!
