On the December 28 installment of 'Radio Star,' Seungri opened up about getting hurt by the last person he dated. 

Taeyang shared, "Seungri thought that they were dating. He even told us that they dated for about a year." G-Dragon added, "She and I had a mutual friend, so I asked my friend. But the girl denied that they were dating." 

Seungri defended himself and explained why he believes that they dated, saying, "I really liked her...We exchanged handwritten letters, and I even talked to her mom on the phone." 

There was a funny moment while he was talking about calling the girlfriend's mom because Seungri slipped out a Japanese word, which seemed to indicate that the girl was Japanese. G-Dragon made fun of the moment, saying, "Is she from Osaka or something?" 

Seungri explained, "I was really hurt and traumatized by the fact that she denied our relationship...probably because she was dating someone else at the same time. Since then I haven't had a girlfriend."
