On March 8th, Girls' Generation made an appearance in "Guerilla Date" segment of KBS' "Entertainment Weekly".
During an interview, the MC asked Yoona,"Is there anyone you share your problems with?", to this she answered that she shared them with her family and friends.
Then the MC suddenly asked,"Is there anyone else?" in which he indirectly mentioned Lee Seung Gi as her boyfriend, and Yoona jokingly answered,"I don't know anyone like that".
Yoona and Lee Seung Gi confirmed their relationship back in January.
