It's just because he likes "Mr.Chu" too much.

On July 4rd, to commemorate Naver StarCast 1st anniversary, Taeyang and Seungri were featured in 'STARCAST ON AIR' special live event and answered some of the questions.

When they were asked which female artist that they wanted to go on a vacation with, to this Taeyang answered,"This is a hard question. I don't have any, if there was I would say the name out loud" then he picked Tablo's daughter, Haru and said,"I wanted to have an ice-cream date with Haru but she was sick...If I have a chance I want to go and play with her".

Seungri then chose A Pink and said,"Personally I like everyone in A Pink. This is my first time saying this. I also saw the choreography for "Mr.Chu" and even sang and danced to the song.
