Monster's Ball is a 2001 American erotic romantic drama film directed by German-Swiss director Marc Forster starring Billy Bob Thornton, Halle Berry, and Heath Ledger. The film tells the story of a poor Southern woman who falls for a widowed prison-guard after the execution of her husband.

The Monster Ball Tour was the second worldwide concert tour by American singer Lady Gaga. Staged in support of her extended play The Fame Monster (2009) and comprising a set list of songs from that and her debut album The Fame (2008), the tour visited arenas and stadiums from 2009 through 2011. Described as "the first-ever pop electro opera" by Gaga, the tour was announced in October 2009 after an intended joint concert tour with hip-hop artist Kanye West was suddenly canceled. The Monster Ball Tour commenced four days after the release of The Fame Monster in November 2009.
