Seoul - MS Team Entertainment announced on Monday that Lee Min Jung, the actress wife of Korean star Lee Byung Hun, is 27 weeks pregnant.
It admitted that it "was cautious in announcing (the pregnancy) due to the recent unsavoury developments".
"She tries to do what is best for the family," it added.
The baby will be their first child. The news came as the scandal and court case revolving around her husband headed to a conclusion.
He was recently at the centre of a highly publicised court case in which he was blackmailed by model Lee Ji Yeon and Kim Dae Hee, a member of girl group Glam.
The two were sentenced last Thursday for attempting to extort 5 billion won (S$6 million) from the actor by threatening to expose a video clip in which he is heard making lewd advances to the model.
Lee, the model, said she had been romantically involved with the actor.
But the court threw out her claims, saying that she had only dealt more damage to Lee Byung Hun by sticking with the story.
Lee Ji Yeon reportedly received a sentence of a year and two months in prison, while Kim had one year in jail.
Lee Min Jung is to give birth in April and she plans to stay in South Korea to make preparations, the agency said.
