KUALA LUMPUR, Malaysia — Beyonce Knowles has sung about partying like a "naughty girl," but Malaysians can expect her to be on her best behavior for a concert in this Muslim-majority country next month, the event’s organizer said Thursday.

The R&B superstar has attracted criticism in recent days from the Pan-Malaysian Islamic Party, the country’s largest opposition group, which wants authorities to scrap the Oct. 25 show because it would promote "Western sexy performances."
