Alicia Keys has apologised to fans in Indonesia after discovering one of her forthcoming concerts was sponsored by tobacco firm Philip Morris.

Billboard posters for the Jakarta gig, which takes place on 31 July, featured a logo for the A Mild cigarette brand.

In a statement, Keys said she asked for "corrective actions" as soon as she learned of the advertisements.

As a result, she added, the company had withdrawn their sponsorship and all signage had been removed.

The Grammy-award winning singer had been criticised by anti-smoking campaigners, who claimed the deal would encourage young fans to take up smoking.
