Lee is 27 weeks pregnant and is expected to give a birth to a child in April, the agency, MS Team Entertainment, said in a press release. The couple got married in August 2013.
The actress will stay here (in South Korea) to make preparations as her delivery date nears, the agency said.
The news comes after the singer and model were given jail terms for attempting to blackmail the actor. On Jan. 15, the Seoul Central District Court sentenced model Lee Ji-yeon and girl group GLAM member Kim Dae-hee to 14 months and one year in jail, respectively.
