Kim Ji-hoon, a former member of the male duo band 'Duke,' has become a father before getting married.

His fiancee delivered a 2.8 kg baby boy Tuesday morning. The mother and baby are both in good condition.

An official at Kim's management agency says the singer teared up at the birth of his first child and that he's also now feeling more responsible.

The couple will marry in April. Kim and his family visited Busan in March to meet with her family and the marriage has been approved. His fiancee "Lee," four years his junior, once worked at an entertainment agency.

A friend introduced Kim to Lee early last year. They wanted to tie the knot last summer but decided to delay the marriage according to both families' wishes.
