Biografia Nasce il 5 agosto 1987 a Independence (in Louisiana) e ha origini irlandesi. Sua madre muore in un incidente stradale quando ha sei anni e viene quindi data in affidamento per due anni, fino a quando è adottata da una famiglia stabile. Vive con loro fino ai dodici anni, finché viene nuovamente presa sotto la tutela dello Stato quando alla madre adottiva è diagnosticato un cancro che, secondo quanto affermato dal cugino adottivo, rende troppo gravoso per la donna doversi prendere cura della figlia adottiva.
Carriera
Nel 2006, all'età di diciotto anni, mentre lavora in una videoteca, viene approcciata da uno scopritore di talenti che l'aveva notata sulla sua pagina Myspace, che la convince a entrare nell'industria del porno: tre mesi dopo gira le sue prime scene di fellatio e a sfondo lesbico.
Nel 2011 è inserita nella lista di CNBC come una delle dodici più popolari pornodive, in virtù dei numerosi premi e candidature ricevuti da Adult Video News (AVN) e XBIZ e della popolarità del suo sito web personale, uno dei principali dell'industria del porno. Nel maggio 2013 è eletta Pet of the Month per Penthouse e Pet of the Year nel 2014. Nel 2015 fa il suo debutto come attrice in un film non pornografico, quando interpreta il ruolo di Hera nel thriller d'azione Samurai Cop 2: Deadly Vengeance, insieme alla collega Kayden Kross e con Tommy Wiseau.
Nel 2016 conduce il reality show Sex Factor insieme ad Asa Akira, Keiran Lee, Remy LaCroix e Tori Black. Nel 2019 è stata inserita nella Hall of Fame degli AVN Awards, prima del ritiro avvenuto nel 2022.
Vita privata
Dichiaratamente bisessuale, Belle è un'attivista per il benessere degli animali.
