February 7 was a big day for some idol stars, who graduated from high school today, while other stars kept it low key, staying in with their pets or hanging out with their friends.

All in today′s Twitter Roundup.

Girls’ Day member Hyeri tweeted two selcas on February 7, writing “Whoa~~~~Haha I finally graduated!! I can’t believe it, I’m sad and sorry.. ㅠㅠ I can’t believe I’m 20 years old.. Thank you to the fans who came out today. I wanted to take the wreaths homes but resisted haha^^ Welcome age 20!!!!!!!!”

Idols – they grow up so fast!

B.A.P’s Jong Up, who also graduated today, tweeted a photo of himself with a simple, “Graduation.”

Congratulations kids!

Later that day, B.A.P′s Dae Hyun tweeted a photo of a poster promoting the idol group′s upcoming concert. Dae Hyun couldn′t contain his excitement as he wrote, "Wow."

Who else is pumped for the concert?

U-Kiss’ Soo Hyun tweeted a photo with his members on February 7 with the message, “u~~~~~~~kiss!!!!!!!!!!!!!!!!!!!!! Everyone’s here, everyone hahaha.”

Soo Hyun managed to squeeze the members into the self-shot photo, and we all know that’s not an easy task.

CN Blue’s Jung Yong Hwa tweeted on February 7, “Finally revealing my new studio! Hahaha. After working in a tight space, it feels great to work in such a great roomㅠ Haha See you on the radio~~”

With coffee in hand Jung Yong Hwa is ready to get to work. Remember to take a break, Jung Yong Hwa!

The day before, CN Blue’s Min Hyuk posted a photo of Lee Jung Shin just being his handsome self and included an ode for his fellow member, writing on February 6, “Lee Jung Shin…His legs are massive, choijangshin (long body). That’s why he’s Lee Jang Shin. Because he’s good at acting, his nickname is Gam (sense) Jung Shin. Looking at the script on his cell phone, choishinshik (the latest style). Min Hyuk, who is envious of his tall height, his Twitter, is eereonshik (like this)….”

Why Min Hyuk doesn’t write more songs for CN Blue, we have no idea.

SISTAR’s maknae Dasom of KBS’ Shut Up Family, which aired its final episode on February 6, tweeted on February 7, “Thank you for loving ‘Family’ these last six monthsㅠㅠ. Thanks to all of your love, I was able to film happily and energetically. I will continue to work hard, so please keep watch~ Thank you♥”

Dasom included a selca of herself smiling sadly, but we’re sure we’ll be seeing the SISTAR member again soon.

ZE:A’s Kwang Hee tweeted a photo of himself at a slumber party(?) on February 6 with the message, “Aigo, pretty~~Haha.”

Kwang Hee is in a bed of dolls and stuffed animals. Creepy or cute? We’ll let you decide.

The next day, fellow ZE:A member Im Si Wan tweeted a photo of himself fast asleep with the brief message, “Goodnight.”

The idol star’s image takes the back seat as Im Si Wan has taken off for la la land in the photo, mouth hanging open. Sweet dreams, Im Si Wan.

Super Junior’s Kyuhyun kept it low key on February 6, tweeting a photo with his friends along with the message, “I came to a pension with my middle school friends to receive some healing…but I’m exhausted from [playing] foot volleyball and futsalㅜㅜ. Receiving healing again while eating meat.”

Kyuhyun knows - food is the best medicine.

Another Super Junior member, Choi Siwon, made an appearance on f(x) member Amber’s Twitter, when she tweeted a photo with him on February 6, writing, “Siwon oppa looks like a British soldier. He has the same smile in every photo…That’s why I poked him.”

He’s real, Amber! But how cute do these two look in their matching blue button-ups?

Meanwhile, miss A’s Jia tweeted about another boy on February 6, posting a photo of a character she drew with the caption, “My BF~~”

Jia’s furry friend inherited her interesting taste in men, as she later tweeted a photo of her cat with the same drawing, writing, “Sunday~~you like him??~~??”

Who needs boys when you have a cat…and a drawing…?

Big Bang′s Taeyang hit the gym with 2NE1′s CL on February 6, tweeting a photo of himself with his YG label mate and the message, "Work out!!!!"

It′s nice to see the YG artists just ′hanging around.′ And if you′re cool like CL, it′s okay to wear sunglasses indoors.

Taeyang and CL weren′t the only YG artists putting some time in at the gym recently, as the agency′s resident trainer Hwang Trainer tweeted a photo of singer Se7en′s scuplted back on February 7, writing "Choi Dong Wook fighting!"

Here′s some motivation for you fellas to get a head start at the gym.

Ailee took off for the Grammys on February 7, tweeting a photo of herself looking rockstar cool with the message, "At Incheon aiport!! See you all in LA!!!"

We know Ailee will do K-Pop proud!
