Bollywood superstar Hrithik Roshan has apologised for hurt caused to "religious or other sentiments" by his controversial comment on "affair with the Pope". He says it was unintentional.

"Seems my tweet about His Holiness has led to misunderstanding. My apologies for hurt caused to religious or other sentiments. Was unintentional," Hrithik posted on Twitter late on Saturday night.

The popular actor had landed himself into legal trouble when a Christian group slapped a notice on him for hurting religious sentiments.

The "Krrish" star is already in a legal tussle with Kangana Ranaut, in an indirect tweet to whom he had posted on social media: "There are more chances of me having had an affair with the Pope than any of the (I'm sure wonderful) women the media has been naming."

This comment neither went down well with Kangana, nor was it appreciated by members of the Indian Christian Voice, an organisation representing the larger interests of the Christian community, including Roman Catholics, in India.

Abraham Mathai, the group's All India president, had sent the legal notice to Hrithik.
