Hayley Carline (born 1985), better known as Ava Leigh, is a British reggae singer from Chester, England. Her debut album, Turned-On Underground, was recorded in 2008; it was released as a promo CD titled Rollin', but never received a full release after the singles “La La La” and “Mad About the Boy” did not achieve commercial success. Leigh released a four-track EP of recordings from the album in January 2009.

Leigh’s song “Mad About the Boy” was featured in the film Angus, Thongs and Perfect Snogging, and her cover of “Mas Que Nada” was featured in a 2008 TV commercial for Next. Leigh also co-wrote Joss Stone’s 2008 single “Governmentalist”.
