Singer Janet Jackson has become a Muslim following her marriage to Wissam Al Mana in 2012 and has toned down her raunchy costumes and dance moves following conversion.

The 49-year-old who married Muslim billionaire Wissam Al Mana, 40, is reportedly taking the religion so seriously that she changed her trademark moves on the stage as well as her flashy attire.

"She feels like she has found a home with her new religion and has told members of her family, who completely respect her choice," a source told The Sun.

"She has spent a great deal of time studying the religion and its followers. The days of raunchy dance moves and sexual lyrics are long gone for Janet, the source said.

The newspaper reports that Janet even ends her Unbreakable world tour shows with "Insha Allah" which means "Allah willing".

Meanwhile, Jackson has pulled out of the iHeartRadio Music Festival this weekend.
