"The Big Bang" is a song written, produced, and performed by Rock Mafia. The song has been used in commercials promoting the syndication of the television series Mob Wives. The song appears on the soundtrack for EA Sports game, FIFA 12 and was re-recorded in Simlish for The Sims 3 and included in the Pets expansion. The song appeared in the 2012 film LOL, starring Miley Cyrus and Demi Moore.

A cover version by singer Katy Tiz was released in 2014 on Rock Mafia's RMR label; it has been aggressively promoted by Clear Channel pop radio stations, and by IHeartRadio.

The music video for "The Big Bang" was filmed on June 10, 2010, and released on November 1, 2010. It features Miley Cyrus and Kevin Zegers. Billboard.com said the video was "the latest stop on Miley Cyrus’s path to prove that she’s a fully grown woman and ensure that she is never called Hannah Montana again." Kevin is working, remembering his girlfriend, when Miley drives by. The video then shows how their relationship progresses, ending with them getting into a car crash. He realizes that his girlfriend only appeared as a ghost.

In November 2010, MTV reported that Rock Mafia's Tim James had stated that a film adaptation of the music video was being planned. On January 11, 2011, E! News confirmed that Cyrus' mother, Tish Cyrus had been meeting with Suzanne Todd (who has worked on films such as Memento, the 2010 adaptation of Alice in Wonderland, and the Austin Powers films) to discuss the music video being created into a feature film with Cyrus to star. MTV reported that Zegers had not yet showed his intention to join the project.
