Does Jonghyun have abs?

Key confirm have abs. My friend say Jonghyun also have abs because he and Key's shirt size is baggy, tight and something else. Then Taemin, Onew and Minho shirts is tight and something else. I have been debating with myself from since the time I started loving Jonghyun until now... But maybe he have. Because you look at his last time muscles and now the muscles - he worked out a lot! If he really have abs hor, that means he's like the hottest member in the group - with abs, pecs (chest muscles) and thick arm muscles.... OMG. I'm hyperventilating nows... >.<"
