"Legends of the Blue Sea" actress Jun Ji Hyun is set to become a proud mother of two soon and as she is into her last few weeks of pregnancy, she finally revealed when the bun in the oven is due.

According to Soompi, the 36-year-old Hallyu star's agency, Culture Depot, announced on Thursday that she is already 36 weeks pregnant and expected to give birth to a baby boy at the end of January 2018. Other details on her delivery are not provided.

Currently, she is said to be on hiatus to focus on prenatal care and prepare for the arrival of her family's newest member.

Jun is married to Choi Joon Hyuk, a banker at the Bank of America who is also the grandson of famed Hanbok designer Lee Young Hee. They were originally childhood friends and dated for a year before tying a knot at the Shilla Hotel, Seoul in April 2012. After the wedding, they were spotted on honeymoon in Rome and other locations.

The couple announced their first pregnancy after the release of her movie "Assassination" in July 2015 and welcomed their first son seven months later in February 2016. They were most recently spotted dining with acquaintances at a Hong Kong restaurant earlier this month.

One of the most in-demand celebrities in South Korea, Jun has been active in the industry for roughly 20 years now. Aside from "Legend of the Blue Sea," Jun is also known for her role in 2001's "My Sassy Girl," one of the highest-grossing Korean comedies of all time, which got a Hollywood remake starring Jesse Bradford and Elisha Cuthbert.

Her other notable acting credits include the classic films "Windstruck," "Il Mare," and "The Thieves" as well as the TV drama "My Love from the Star," which marked her small screen comeback since appearing in 1999's "Happy Together."
