Sometimes, being a celebrity calls for doing things you've never done before, whether it's riding a horse, throwing water in someone's face, or.... even kissing (all right, all right, in some cases, more like "pecking/bbobbo on the lips" - still counts)!

Check out these celebs who debuted at a young age with little experience in the romantic field so that they gave their first kiss away on screen and had it witnessed by everyone!

T-ara's Jiyeon

She stated on a show that her first kiss was with her ideal type at the time, Yoo Seung Ho, for T-ara's "Lies" MV.  However, note that she created a controversy by giving two different accounts of her first kiss, so this may not be the actual case, but still cute to note. You can see above at around 1:03.

UEE

UEE also said she had her first kiss with Yoo Seung Ho for an MV (@3:25), specifically Jo Sung Mo's "Please Take Good Care of Her," but she, like Jiyeon, said in another show that her first kiss was with someone else… a former trainee to be exact.  Perhaps the two ladies aren't considering their MV-related kisses as their first actual kiss? That could explain everything…

Dohee

She revealed that her kiss scene with Kim Sung Kyun, who is fourteen years older, in 'Reply 1994' was her very first.  Apparently, before the kiss, Kim Sung Kyun was jokingly threatened by the producer "not to use tongue" and Dohee threw up after from seasickness.

Moon Geun Young

The actress started at a young age and, fittingly enough, had her first kiss through movie 'My Little Bride' with Kim Rae Won!  She was nervous and helped ease Kim Rae Won, who felt sorry for taking her first kiss.

Jo Kwon

The 2AM member revealed his first kiss was with none other than Lizzy for their sitcom 'All My Love'!

Gyuri

Before she was a member of KARA, Gyuri was known to be a pretty child actress, and she revealed, a bit disturbingly enough, that her first kiss was stolen from her by Kang Ho Dong! The two were in a show together called 'Sonagi' in which she played Kang Ho Dong's younger brother's girlfriend.  Eighteen years her senior in real life, he made her look away and when she turned back to look at him, he kissed her on the lips with "blood sausage" lips, as Gyuri said.  She was only about seven.

Jin Se Yeon

This actress revealed she had no dating experience, so she experienced her first peck with Lee Ji Hoon and first kiss with Choi Jin Hyuk in drama 'My Daughter The Flower.'

U-KISS's Kevin

He revealed his first kiss was with senior singer Bae Seul Gi and Han Ye Won for musical 'On Air Live.'

Thunder

When MBLAQ made a CF with Jiwon, now in Spica, for 'Chapstick,' it turned out that the member who kissed her was none other than Thunder!  And that was his first kiss.

Jin Ji Hee

Smooth, kid, smooth!  Child actress Jin Ji Hee revealed that while filming the MV for K.Will's "Gift," she leaned into kiss her opposite star, Wang Suk Hyun, on the cheek, but he suddenly turned his head, resulting in a smooth and lots of laughter at 5:08.  Turns out that was her first kiss!

Nam Ji Hyun

Child actress had her first kiss with Kang Ha Neul for 'Angel Eyes'!  She was a bundle of nerves which actually helped sell the young love vibe.

Kim So Hyun & Yeo Jin Goo

They had their first "kiss" (really just a peck) for their drama 'Missing You.' Kim So Hyun tells a hilarious tale on 'Strong Heart' of getting tips from Kim Yoo Jung, getting NGs because Yeo Jin Goo stuck his lips out, and being comforted later by him even though she wasn't thinking much of it.
