K-pop superstar Rain was baptized into the Catholic faith earlier this month, apparently encouraged by his devout girlfriend, the actress Kim Tae-hee.
Rain's conversion has fuelled speculation that they are about to get married.
The star's agency Cube DC said Rain was baptized on July 10 in a cathedral at the Namhansan Fortress Catholic martyrs' site in Gwangju, Gyeonggi Province.
Kim, her mother and actor Ahn Sung-ki were among those present. Rain was baptized alone rather than, as is customary, with a group of other converts.
Rain and Kim's relationship has been common knowledge since January last year, when Rain caused a scandal by bunking off his military duties to be with her. He was discharged in July.
