"Harry Potter" star Emma Watson has joined a campaign by Turkish women to rebel against a politician who recently branded females "indecent" for laughing in public.

Watson is an ambassador for United Nations Women. She joined the rebellion and shared a photograph of herself having a giggle at an outdoor restaurant. It has been reposted more than 15,000 times, reports contactmusic.com.

Earlier this week, the Turkish Deputy Prime Minister Bulent Arinc insisted honest women should not laugh in public because it is disgusting.

Females staged a protest on Twitter.com, setting up a campaign with the hashtag #DirenKahkaha, which translates to Resist Laugh, and posted pictures of themselves laughing in open spaces.
