There has been talk about Lee Bum Soo and Girls Generation Yoona starring in KBS' new drama "The Prime Minister and I" as the male and female lead roles.

According to multiple sources on September 11, Lee Bum Soo and Yoona will most likely be starring in the drama together as the lead roles. Lee Bum Soo's casting has been confirmed, and Yoona is the main candidate for the lead female role, currently under review.

"Prime Minister and I" is the Korean adaptation drama of "The Sound of Music," and tells the story a female tutor coming to live at the house of the prime minister. In the drama Lee Bum Soo will play the prime minister role, and Yoona was offered the role of the tutor.

One of the reasons why the drama casting is the center of attention is because Lee Bum Soo and Yoona have a huge age difference between them. One broadcast rep said, "I can't wait to see how Lee Bum Soo, who was born in 1970, and Yoona, who was born in 1990, will collaborate for this new drama."

"Prime Minister and I" is scheduled to air its pilot episode sometime in December.
