Can anyone tell me the name of this song? Warning: I have little to no info. It'll be a challenge.?

Okay. So I heard a song in Forever 21 that I really liked. I can only remember like four lyrics. It was something along the lines of "Hey there pretty lady" and it's very up beat and sort of reminiscent of owl city though not as synthesized. It's a guy singing and the song is very odd and random but I liked and now I don't know if I shall ever be able to find it. Sorry that's all the info I have.
