Not only has G-Dragon been doing Park Bom's eye trademark, but he's also been doing a cat-like motion in his part of the 'I Need a Girl' performances and also the MV. Although Park Bom doesn't really do that a lot, she has been seen to do it once in a picture. The above picture shows her trying to be cat, kekeke.

A little interesting fact is that, G-Dragon said in an interview that he likes girls that are like cats. (Someone correct me if I re-phrased it wrong)

Here are more pictures of G-Dragon doing that motion.
