○ Fans called her as the ''Second BoA'' by debuting in a young age like BoA.

○ Because her speaking voice is so low, she often got mistaken for a boy when she was younger.

○ While preparation time for Lee Hi’s debut was short, she was one of the rare few trainees that received on-on-one supervision from Yang Hyun-syuk in the process.

○ She’s also one of the rare few YG Entertainment trainees that has had no dance training whatsoever. Hence, she’s a pretty clumsy dancer in comparison.

○ Due to her amazing voice, she's considered as the ''Korea's Adele.''

○ To celebrate Lee Hi’s debut, super big balloons in the shape of “1, 2, 3, 4” were tied to the roof of the YG Entertainment HQ in South Korea.

○ She was featured in  Epik High's comeback, ''It's cold.''

○ Her second single, “Scarecrow”, was in fact not a new song. It was written five years ago and it was supposed to be Park Bom’s (2NE1) solo debut song, but YG's CEO hide it just for her.

○ Although she has started out as a solo artiste, Lee Hi is expected to debut as a member of forthcoming YG Entertainment girl group, “SuPearls” in the future.

○ Lee Hi once said that her “ideal guy” is labelmate and senior Choi Seung-hyun aka T.O.P from BIGBANG.

○ The music video for “1, 2, 3, 4” looked simple but apparently, it cost 2.5 times more to produce than other YG Entertainment artiste’s music videos.
