Park Shin Hye posted a highly amusing photo on her Instagram account showing her hand covered with Lee Jong Suk's signature. Her Pinocchio co-star was in the middle of signing a stack of photos when Park Shin Hye jokingly held her hand out. Her photos show the end result. Even an A-list celebrity can have a fangirl moment!

Watch Park Shin Hye and Lee Jong Suk in Pinocchio:

Her caption says the following in English.

"#Pinocchio #GiHaMyoung? #ChoiDalPo? #LeeJongSuk #ChoiInHa #OowaOppaGiveMeYourAutographPlease #SettingForFilming "I hold out my hand to you who was autographing on the paper, and you autographed on my hand." I didn't expect you to really do that. #ThankyouOppa #WowIGotOppa'sAutograph

Too funny! I wish Lee Jong Suk would sign my hand as well! I just love the playful (and skinship filled) chemistry between these two.
