Appearing via phone call on the latest episode of KBS's 'Mamma Mia', 'Nice Guy' Song Joong Ki revealed that he still didn't let most other celebrities into his private life despite his growing popularity.
Hosts Lee Young Ja and Super Junior's Kyuhyun asked him what his mother's reactions were when he invited friends over to his house. "Even after I debuted, she treats them well and makes them good things to eat," he responded.
However, he didn't have much of a sample to go on. "Lee Kwang Soo was the only one who's been to my house," he confessed.
Picking up this tidbit of information, Kyuhyun suddenly asked, "Can I be the second one to visit your house?" to which Song Joong Ki agreed gladly.
