I guess I'll answer last question 1st ^o^
I really think Alan looks like a mix of Changmin, Sungmin and JJ. How cool !!
About celebrities look-a-like.
Well, I have a friend who often compares me to UEE... She says I have big eyes and long beautiful hair (well, before I cut it down T.T it's growing back fast enough). I don't know how I should take it, but she a UEE's fan and I like her too. I just think her eyes are weird (surgery, I know...).
Another friend told me I looked like her SNSD's favorite member, SooYoung.
I'd love to look like Moon Geun Young (you know, 1st female lead in Cinderella Sister), I think she's really gorgeous.
Yoon Eun Hye also (eternal love haha). But most of all, SNSD's Tiffany. Oh my I want it bad! Otherwise it'd be Taeyon. XD Or Sulli !
