Singer and actor Lee Seung-gi and actor Lee Da-in welcomed a baby girl on Monday, Lee Seung-gi's agency said.

"Both the mother and the baby are healthy, and Lee Seung-gi is overjoyed with the new arrival," the agency HumanMade said.

The couple tied the knot in April last year, more than two years into their relationship.

Last year, Lee Seung-gi hosted cable channel JTBC's "Peak Time," a reality competition show that shed light on K-pop boy bands that have already debuted.

Lee Da-in, a daughter of veteran actor Kyeon Mi-ri, is known for starring in "Come and Hug Me" (2018), "Dr. Prisoner" (2019) and "Alice" (2020).
